(Use symbolic notation and fractions where needed.) v(t) = When is the object at rest? (Use symbolic notation and fractions where needed.) t = The function s(t) = 9 – 15t + 8t² describes the distance s from the origin at time t of an object in rectilinear motion. Find the velocity v of the object at any time t. (Use symbolic notation and fractions where needed.) v(t) = When is the object at rest? (Use symbolic notation and fractions where needed.) t =
At time t = 15/16, the object reaches a state of zero velocity, indicating a momentary pause in its motion. Prior to this time, the object moves in one direction, while after this time, it changes direction and moves in the opposite direction. The value t = 15/16 represents the specific moment when the object transitions from one direction to another and experiences a brief period of rest.
To find the velocity v(t) of the object at any time t, we differentiate the given distance function s(t) = 9 - 15t + 8t² with respect to time:
v(t) = d/dt (9 - 15t + 8t²)
Applying the power rule of differentiation, we obtain:
v(t) = -15 + 16t
Therefore, the velocity v(t) of the object at any time t is given by v(t) = -15 + 16t.
To determine when the object is at rest, we set the velocity v(t) equal to zero and solve for t:
-15 + 16t = 0
Adding 15 to both sides of the equation, we have:
16t = 15
Finally, dividing both sides by 16, we find
t = 15/16
Hence, the object is at rest when t = 15/16.
This means that at time t = 15/16, the object's velocity is zero, indicating that it is momentarily stationary. Before this time, the object is moving in one direction, and after this time, it is moving in the opposite direction. The value t = 15/16 represents the specific point in time when the direction of motion changes, and the object is at rest for an instant.

An airplane starts from rest and accelerates at 6.99 m/s2. what is its speed at the end of a 500-m runway?
The speed of the plane at the end of the runway is 59.065 m/s.
Evaluation :The equations of position and velocity in function of time of an object moving in a straight line together constant acceleration are the following:
x = x₀ + v₀ · t + 1/2 · a · t²
v = v₀ + a · t
Where:
x = position of the plane at time t.
x₀ = initial position.
v₀ = initial velocity.
t = time.
a = acceleration.
v = velocity of the plane at time t.
If we place the origin of the frame of reference at the starting point, then x₀ = 0. Since the plane originate from rest, v₀ = 0. Then, the equation gets reduced to this:
x = 1/2 · a · t²
Let's find how much time it takes a plane to travel 500 m:
500 m = 1/2 · 6.99 m/s² · t²
2 · 500 m / 6.99 m/s² = t²
t = 8.45 s
Now, let's use the equation of velocity to solve the speed of the plane at t = 8.45 s (the time at which the plane is at the end of the runway):
v = v₀ + a · t (v₀ = 0)
v = a · t
v = 6.99 m/s² · 8.45 s
v = 59.065 m/s
The speed of the plane at the end of the runway is 59.065 m/s.

A hydraulic lift is used to lift a car that weighs 1400 kg. The foot pedal is attached to a piston that has an area of 50 cm2. This is attached to a lift with a large piston with an area of 4400 cm2.a. What force needs to be applied to the small piston in order to lift the car?b. How far will the smaller piston need to be pushed in order to raise the car by 2 meters?
The smaller piston needs to be pushed approximately 176 meters to
raise the car by 2 meters
a. To determine the force needed to lift the car using the hydraulic lift,
we can use Pascal's law, which states that the pressure in a fluid is
transmitted equally in all directions.
The formula for calculating the force exerted by the hydraulic lift is:
Force = Pressure * Area
Given:
Area of the small piston (A₁) = 50 cm²
Area of the large piston (A₂) = 4400 cm²
Weight of the car (W) = 1400 kg (weight is equivalent to mass multiplied
by acceleration due to gravity, which is approximately 9.8 m/s²)
First, we need to find the pressure exerted by the small piston:
Pressure₁ = Force₁ / Area₁
Since the pressure is transmitted equally, we can equate the pressure in
the small piston to the pressure in the large piston:
Pressure₁ = Pressure₂
Force₁ / Area₁ = Force₂ / Area₂
Substituting the given values:
Force₁ / 50 cm² = W / 4400 cm²
Solving for Force₁:
Force₁ = (W / 4400 cm²) * 50 cm²
Converting cm² to m²:
Force₁ = (W / 4400) * 0.005 m²
Substituting the weight of the car:
Force₁ = (1400 kg / 4400) * 0.005 m²
Calculating the force:
Force₁ = 2.84 kN (rounded to two decimal places)
Approximately 2.84 kilonewtons of force needs to be applied to the
small piston to lift the car.
b. To determine how far the smaller piston needs to be pushed to raise
the car by 2 meters, we can use the concept of equal pressure in the
hydraulic system.
The ratio of the distances moved by the small piston (d₁) and the large
piston (d₂) is equal to the ratio of their respective areas:
d₁ / d₂ = A₂ / A₁
Substituting the given values:
d₁ / d₂ = 4400 cm² / 50 cm²
Simplifying:
d₁ / d₂ = 88
We know that d₂ is 2 meters. We can substitute this value and solve for d₁:
d₁ / 2 m = 88
d₁ = 88 * 2 m
d₁ = 176 m

a force is applied to a particle along its direction of motion. at what speed is the magnitude of force required to produce a given acceleration twice as great as the force required to produce the same acceleration when the particle is at rest? express your answer in terms of the speed of light.
The speed of light as a reference point, as relativistic effects become significant at speeds approaching the speed of light.
The magnitude of force required to produce a given acceleration twice as great as the force required to produce the same acceleration when the particle is at rest can be found by using Newton's second law, F = ma. When the particle is at rest, the force required to produce the given acceleration is F0 = ma.
To find the force required when the particle is in motion, we can use the relativistic expression for force, which incorporates the concept of relativistic mass:
F = γm0a
Where F is the force, γ is the Lorentz factor (γ = 1/√(1 - v²/c²)), m0 is the rest mass of the particle, a is the acceleration, v is the velocity of the particle, and c is the speed of light.
We want to find the velocity at which the force required to produce the acceleration is twice the force required when the particle is at rest. So, we can set up the following equation:
2F0 = γm0a
Solving for v, we can substitute the expression for γ and rearrange the equation to obtain:
v = c√(1 - (2F0/ma)²)
This equation gives the speed in terms of the speed of light (c).

The mass of the ice that melts when a bullet of mass 4 grams moving at a speed of 3000 meters per second is stopped by an ice block at 0 degrees Celsius is 0.00006 kg.
The kinetic energy of the bullet is converted to heat energy when it collides with the ice block. We can calculate this heat energy as follows:
Initial kinetic energy of the bullet, E = (1/2)mu² = (1/2)×0.004×(3000)² J = 18 J
This is the amount of heat energy that is produced when the bullet collides with the ice block. This heat energy is used to melt a certain mass of ice.
We can calculate the mass of ice melted using the formula for heat of fusion:
Q = mLf
where Q is the heat energy absorbed by the ice, and m is the mass of ice melted.

An object located near the surface of Earth has a weight of a 245 N
object?
• What is the mass of the object?
• What is the weight of the object on Mars where the gravity is
3.72 m/s?
Answer:
The mass of the object is 24.5 kg and weight of the object on Mars is 91.14 N.
Explanation:
Weight of the object on the surface of Earth, W = 245 N
On the surface of Earth, acceleration due to gravity, g = 10 m/s²
Weight of an object is given by :
W = mg
m is mass
\(m=\dfrac{W}{g}\\\\m=\dfrac{245\ N}{10\ m/s^2}\\\\=24.5\ kg\)
So, the mass of the object is 24.5 kg
Acceleration due to gravity on Mars, g' = 3.72 m/s²
Weight of the object on Mars,
W' =mg'
W' = 24.5 kg × 3.72 m/s²
= 91.14 N
So, the weight of the object on Mars is 91.14 N.
Given the data in the question;
Weight of object; \(W = 245N\)
What is the mass of the object.Weight the measure of the force of gravity pulling down on a particle or object.
It is expressed as:
\(W = m* g\)
Where m is mass of the object and g is acceleration due to gravity { Acceleration due gravity of Earth \(g_{earth} = 9.8m/s^2\) }
We substitute our values into the equation
\(245N = m * 9.8m/s^2\\\\245kg.m/s^2 = m * 9.8m/s^2\\\\m = \frac{245kg.m/s^2}{9.8m/s^2} \\\\m = 25kg\)
Therefore, mass of the object located near the Earth surface is 25kg
Weight of the object on Mars where the gravity \(3.72m/s^2\)
So on planet Mars; \(g = 3.72m/s^2\), we know that mass of the object is \(25kg\)
We substitute into our equation
\(W = m* g\)
\(W = 25kg * 3.72m/s^2\\\\W = 93kg.m/s^2\\\\W = 93N\)
Therefore, the weight of the object on Mars with the given gravity is 93 Newtons.

A car is launched by a spring and goes to the top of a loop. Fill in the energy bar chart by drawing a vertical bar(s) in the correct position (both Initial & Final conditions).
Answer:
A) the initial point all energy is elastic potential and the final point all energy is kinetic
B) a bar graph the two bars have the same height and the sum of their height is the initial energy
C) two bars, one for the kinetic energy and the other for the gravitational potential energy.
Explanation:
A) For this exercise we must use the energy conservation relations
starting point. When the spring is compressed
Em₀ = K_e = ½ k x²
end point, at the bottom of the loop
Em_f = K = ½ m v²
energy is conserved
Em₀ = Em_f
½ k x² = ½ m v²
v = \(\sqrt{ \frac{k}{m} }\) x
In a bar graph the initial point all energy is elastic potential and the final point all energy is kinetic
B) intermediate point in a quarter of the radius
In this case we use the lower part of the loop as the starting point and the quarter part of the bow as the end point.
Em₀ = K
Em_f = K + U = ½ m v² + m g R
in a bar graph the two bars have the same height and the sum of their height is the initial energy
C) End point highest part of the loop
starting point, bottom of loop
Emo = K = ½ m v₀²
from part A of the exercise we saw that it is equal to the elastic energy of the spring
final point. Highest part of the loop
Emf = K + U
Em_f = ½ m \(v_{f}^2\) + mg (2R)
where R is the radius of the loop
Em₀ = Em_f
1/2 m v₀² = 1/2 m v_{f}^2+ mg 2R
v₀² = v_f^2 + 4gR
In a bar graph there are two bars, one for the kinetic energy and the other for the gravitational potential energy. The sum of the heights of these bars is the initial energy, so the energy is transformed but not created or destroyed in the process.

A school bus takes 0.690 h to reach the school from your house. If the average velocity of the bus is 18.7 km/h to the East, what is the displacement.
The displacement is 12.903 km east.
A 69 mH inductor, a 14.5 resistor, and a 1.2 V battery are connected in series. The switch is closed at t = 0. b) Find the voltage drop across the resistor after one time constant has passed.
Answer in units of V
The voltage drop across the resistor after one time constant has passed is approximately 0.757 V.
What is the time constant (τ) for an RL circuit?The time constant (τ) for an RL circuit is equal to the inductance (L) divided by the resistance (R). The time constant (τ) for an RL circuit is given by the formula:
τ = L / R
where L is the inductance in henries and R is the resistance in ohms.
In this circuit, L = 69 mH = 0.069 H and R = 14.5 Ω, so τ = L / R = 0.069 / 14.5 = 0.00476 seconds.
After one time constant has passed, the current in the circuit will have reached approximately 63.2% of its final value. At this point, the voltage drop across the resistor can be found using Ohm's law:
V = IR
where V is the voltage drop across the resistor, I is the current in the circuit, and R is the resistance of the resistor.
The final current in the circuit can be found using the formula:
I = V / (R + XL)
where XL is the inductive reactance of the inductor, given by:
XL = 2πfL
where f is the frequency of the circuit in hertz.
Since the circuit is a DC circuit, the frequency is 0, so XL = 0.
Therefore, the final current in the circuit is:
I = V / R
The voltage of the battery is 1.2 V, so the initial current in the circuit is:
I₀ = V / (R + XL) = 1.2 / (14.5 + 0) = 0.0828 A
After one time constant has passed, the current in the circuit will have reached approximately 63.2% of its final value, so the current at this point is:
I₁ = 0.632 * I = 0.632 * (1.2 / 14.5) = 0.0522 A
The voltage drop across the resistor at this point is:
V = IR = 0.0522 * 14.5 = 0.7569 V
Therefore, the voltage drop across the resistor after one time constant has passed is approximately 0.757 V.
