Answer:

\(\omega '=-13.5rad/s\)

Explanation:

From the question we are told that:

Time \(t=4sec\)

Angular displacement \(\theta= 161 rad\)

Final Angular velocity  \(\omega = 100 rad / s\)

Let

Angular acceleration \(\alpha\)  

Generally the equation for Initial Angular velocity  \(\omega '\) is mathematically given by

\(-\omega '^2=2 \alpha \theta -\omega^2\)

\(\omega '^2= \alpha 328 +11236\)

Also,Initial Angular velocity  \(\omega '\) is mathematically given by

\(\omega '=\omega - \alpha t\)

Therefore substitution

\(-\omega '^2=2 \alpha \theta -\omega^2\)

\(\omega '=\omega - \alpha t\)

\((\omega - \alpha t)^2=2 \alpha \theta -\omega\)

\(-16\alpha^2+848\alpha+11236= \alpha 328 -11236\)

\(16\alpha^2-520\alpha=0\)

\(\alpha=29.875rads/s^2\)

Substitution in the 2nd equation for Initial Angular velocity  \(\omega '\)

\(\omega '=106-(29.875rads/s^2*4)\)

\(\omega '=-13.5rad/s\)

Answer:

We can use the kinematic equations to solve this problem.

Let a be the acceleration and d be the distance traveled at maximum speed.

First, we can use the equation:

d = vt + (1/2)at^2

where v is the maximum speed, t is the time traveled at maximum speed, and a is the acceleration.

We know that the bus takes 21 seconds to travel 270 meters, so the time traveled at maximum speed is:

21 - 2a = t

We also know that the acceleration is twice as great as the deceleration, so we can write:

a = 2d

Then, we can substitute these expressions into the first equation:

d = (20)(21 - 2a) + (1/2)(2d)(21 - 2a)^2

Simplifying and solving for d, we get:

d = 210 - 5.25a + 0.25a^2

To find the acceleration, we can use the fact that the maximum speed is reached at the midpoint of the trip, so the distance traveled at maximum speed is half the total distance:

d = 1/2(270)

Solving for d, we get:

d = 135

Substituting this value into the equation for d, we get:

135 = 210 - 5.25a + 0.25a^2

Simplifying and solving for a, we get:

a = 8 m/s^2

Finally, we can use the equation:

d = vt

to find the distance traveled at maximum speed:

d = (20)(21 - 2a)

Substituting the value of a, we get:

d ≈ 188.4 m

Therefore, the acceleration of the bus is 8 m/s^2 and the distance traveled at maximum speed is approximately 188.4 meters.

Answer:

The magnitude of the total vertical force exerted by the ground on the rear wheels of the truck is 62271.86 N

Explanation:

To find the magnitude of the total vertical force exerted by the ground on the rear wheels of the truck, we need to consider the static equilibrium condition of the truck.

The weight of the truck and its contents acts downwards through its center of gravity (cg) and the normal force exerted by the ground acts upwards. The normal force is distributed between the front and rear axles of the truck according to the position of the cg.

Let F_R be the magnitude of the total vertical force exerted by the ground on the rear wheels of the truck.

Then, from the static equilibrium condition:

Sum of vertical forces = 0

F_R + (8010 kg)(9.81 m/s^2) - F_F = 0

where F_F is the magnitude of the total vertical force exerted by the ground on the front wheels of the truck.

The distance between the cg and the rear axle is given as 0.63(2.3 m) = 1.449 m.

The distance between the cg and the front axle is therefore (2.3 m - 1.449 m) = 0.851 m.

We can assume that the weight is evenly distributed between the four wheels of the truck. Therefore, the weight supported by each wheel is:

(8010 kg)(9.81 m/s^2)/4 = 19653.45 N

Using moments about the rear axle, we get:

F_F(0.851 m) - F_R(1.449 m) = 0

Solving these two equations simultaneously, we get:

F_R = 62271.86 N

Therefore, the magnitude of the total vertical force exerted by the ground on the rear wheels of the truck is 62271.86 N.

The magnitude of the total vertical force exerted by the ground on the rear wheels of the truck is approximately 62,203 N.

Static equilibrium refers to the state of an object at rest when the net force acting on it is zero. In other words, when an object is in static equilibrium, it is not accelerating in any direction and all forces acting on it are balanced.

The principle of static equilibrium states that the sum of all forces acting on an object in static equilibrium is zero, and the sum of all torques (rotational forces) acting on the object is also zero. This principle can be applied to solve problems involving the forces and torques acting on objects at rest.

Static equilibrium is important in many areas of physics and engineering, including structural analysis, civil engineering, and mechanical engineering. Understanding static equilibrium is essential for designing structures and machines that can support loads without collapsing or breaking, and for analyzing the stability of systems in various applications.

Here in the Question,

To find the magnitude of the total vertical force exerted by the ground on the rear wheels of the truck, we need to analyze the forces acting on the truck and apply the principle of static equilibrium, which states that the sum of all forces acting on an object in static equilibrium is zero.

The forces acting on the truck are the weight of the truck and its contents and the reaction forces from the ground acting on each of the four wheels. The weight of the truck and its contents can be represented as a single force acting vertically downwards at the center of gravity (cg) of the truck.

Since the truck is at rest on a horizontal road, the reaction forces from the ground acting on the wheels must balance the weight of the truck and its contents in both the horizontal and vertical directions. The horizontal components of the reaction forces cancel each other out, since the truck is at rest and not moving in the horizontal direction.

To find the vertical forces, we can first find the weight of the truck and its contents:

w = m*g

where w is weight, m is mass, and g is the acceleration due to gravity (9.81 m/s^2).

Substituting the given values, we get:

w = 8010 kg * 9.81 m/s^2 = 78,419.1 N

Next, we can find the position of the center of gravity (cg) relative to the front and rear axles of the truck:

d = L * (m1 - m2) / m

where d is the distance from the cg to the rear axle, L is the distance between the front and rear axles (2.3 m), m1 is the mass of the truck and contents behind the cg, m2 is the mass of the truck and contents in front of the cg, and m is the total mass of the truck and contents.

Substituting the given values, we get:

d = 2.3 m * (8010 kg * 0.63 - 8010 kg * 0.37) / 8010 kg = 0.743 m

Now, we can find the magnitudes of the vertical forces acting on the rear and front wheels of the truck using the principle of static equilibrium. Since the truck is not moving vertically, the sum of the vertical forces acting on it must be zero. Therefore:

Frear + Ffront = w

where Frear is the vertical force exerted by the ground on the rear wheels, Ffront is the vertical force exerted by the ground on the front wheels, and w is the weight of the truck and its contents.

The rear wheels support the weight of the truck and its contents, as well as a portion of the weight shifted forward of the rear axle due to the position of the cg. The front wheels support only a portion of the weight shifted backward of the front axle. To find the magnitudes of the vertical forces, we can use the following equations:

Frear = (m1/m)*w

Ffront = (m2/m)*w

where m1 is the mass of the truck and contents behind the cg, m2 is the mass of the truck and contents in front of the cg, and m is the total mass of the truck and contents.

Substituting the given values and using the value of d found earlier, we get:

Frear = (8010 kg * 0.63 / 8010 kg)*78,419.1 N = 62,202.7 N

Ffront = (8010 kg * 0.37 / 8010 kg)*78,419.1 N = 36,216.4 N

The magnitude of the total vertical force exerted by the ground on the rear wheels of the truck is:

Frear = 62,202.7 N ≈ 62,203 N

Therefore, the magnitude of the total vertical force exerted by the ground on the rear wheels of the truck is approximately 62,203 N.

The correct answer is A) d = v * t

Explanation:

When writing an equation the goal is to represent the equality between different mathematical expressions or elements. Due to this, in an equation the symbol = is always used. Additionally, to translate a sentence into an equation, the variables should be represented using numbers or letters.

For example, in the sentence "The distance traveled is the speed multiplied by the time" there are three variables mentioned: distance, speed, and time. Also, these can be represented through the letters d (distance), v (speed or velocity), and t (time). Besides this, the sentence explains speed should be multiplied by time, which means it should be written as v × t or v * t and this is equivalent (=) to distance or t. According to this, the final equation would be d = v * t.

Explanation:

The centripetal force \(F_c\) experienced by the planet is the same as the gravitational force \(F_G\) so we can write

\(F_c = F_G\)

or

\(m\dfrac{v^2}{R} = G\dfrac{mM}{R^2}\)

where M is the mass of the star and R is the orbital radius around the star. We know that

\(v = \dfrac{C}{T} = \dfrac{2\pi R}{T}\)

where C is the orbital circumference and T is orbital period. We can then write

\(\dfrac{4\pi^2R}{T^2} = G\dfrac{M}{R^2}\)

Isolating \(T^2\), we get

\(T^2 = \dfrac{4\pi^2R^3}{GM}\)

Taking the square root of the expression above, we get

\(T = 2\pi \sqrt{\dfrac{R^3}{GM}}\)

which turns out to be \(T = 2.47×10^7\:\text{s}\). We can convert this into earth days as

\(T = 2.47×10^7\:\text{s}×\dfrac{1\:\text{hr}}{3600\:\text{s}}×\dfrac{1\:\text{day}}{24\:\text{hr}}\)

Take down to be positive.  Given:

v₀ = 0 m/s

a = 9.8 m/s²

t = 12.77 s

Find: Δy and v

Δy = v₀ t + ½ at²

Δy = (0 m/s) (12.77 s) + ½ (9.8 m/s²) (12.77 s)²

Δy ≈ 799 m

v = at + v₀

v = (9.8 m/s²) (12.77 s) + 0 m/s

v ≈ 125 m/s

When a 0.80 Kg block is used in place of a 0.25 Kg block, the length of the string is increased by 19.6 cm.

The formula used by the Hooke's Law Calculator is Fs = -kx, where F is the spring's restoring force, k is the spring constant, and x is the displacement, or the length by which the spring is being stretched

We'll start by determining the spring's string constant. Specifics below:

Extension (e) = 6.0 cm

Mass (m) = 0.25 Kg

Acceleration due to gravity (g) = 9.8 m/s²

Force (F) = mg = 0.25 × 9.8 = 2.45 N

Spring constant (K) =?

F = Ke

2.45 = K × 6

Divide both sides by 6

K = 2.45 / 6

K = 0.40 N/cm

The extension will be calculated after the 0.25 kg block is replaced with the 0.80 kg block. As demonstrated below:

Mass (m) = 0.80 Kg

Acceleration due to gravity (g) = 9.8 m/s²

Force (F) = mg = 0.80 × 9.8 = 7.84 N

Spring constant (K) = 0.40 N/cm

Extension (e) = ?

F = Ke

7.84 = 0.40 × e

Divide both sides by 0.40

e = 7.84 / 0.40

e = 19.6 cm

We may thus deduce from the preceding computation that the spring will lengthen by 19.6 cm.

The velocity of a person or object determines its direction of motion. A scalar is velocity's most basic representation. Velocity is essentially a vector quantity. The relocation change rate is the issue.

The vector quantity velocity (v), denoted by equation v = s/t, quantifies dislocation (or shift in position, s), over change in time (t). Velocity is the pace and direction of an object's movement, whereas speed is indeed the time rate that an object is travelling along a path.
