The ball was moving at 11.1 m/s in the horizontal direction just before it hit the ground.

What is horizontal direction?
Horizontal direction is a term used to describe a direction parallel to the horizon. It is an important concept in navigation and surveying, since it helps to determine a person's geographic location. Horizontal direction is usually expressed as an angle, measured clockwise from the direction of true north. It is important to remember that the angle for horizontal direction increases as the person turns clockwise from true north. For example, if a person were facing north, their horizontal direction would be 0°. If they were facing northeast, their horizontal direction would be 45°. In addition to its use in navigation, horizontal direction is also used in architecture and engineering. For example, when designing a building, architects use horizontal direction to determine which way the building should face in order to maximize the amount of natural light that enters the building.

We can use the equation vf^2=vi^2 + 2ad, where vf is the final velocity, vi is the initial velocity, a is the acceleration due to gravity (9.8 m/s^2) and d is the displacement.
In this case, vf = 0 m/s (since the ball has stopped moving at the end of its fall), vi = unknown, a = 9.8 m/s^2, and d = 3.32 m.
We can rearrange this equation to solve for vi: vi = sqrt(vf^2 - 2ad)
vi = sqrt(0^2 - 2(9.8)(9.47)) = -11.1 m/s
Since the velocity is negative, it is moving in the opposite direction of the displacement. Therefore, the ball was moving at 11.1 m/s in the horizontal direction just before it hit the ground.

Answer: Renewable Resource

Explanation: There isn't a limited supply of water, which makes it a renewable resource.

Answer:

in my view water is the combination of oxygen (1) part and hydrogen (2) part

Answer:

As the temperature is increased the more the energy store

   The value of the acceleration of the earth toward it when it accelerates toward the earth with 9.8m/s² is a = 7.35×10-²³m/s².

   Forces are the definition of Newton's second law, which is stated under the relation:

∑ Force = mass × acceleration.

  In other words, force is the origin of motion since it generates acceleration in a system.

   In this case we must complete the statement:

"A student with mass 45 kg jumps off a high diving board. Using 6. 0×1024 kg for the mass of the earth, what is the acceleration of the earth toward her as she accelerates toward the earth with an acceleration of 9. 8 m/s2 ? assume that the net force on the earth is the force of gravity she exerts on it."

  We determine the Force of the student:

F = ma

F = 45kg * 9.8m/s².

F = 441N

  Now we go to the acceleration of the earth:

a = F/m

a = 441N / 6×10²⁴ Kg

a = 7.35×10-²³m/s².

t1 x = t1cos 40

mgx= 0

T2y= t2 sin 20

t1y= t1 sin 40

mgy= - mg

X and y components of resultant (R)

Rx = t1x -t2x + mgx

Rx= -t2 cos 20 + t1cos 40 (3)

Ry = t2 sin 20 + t1 sin 40 - mg(2)

Rx, and Ry = 0

0 = -t2 cos 20 + t1cos 40 (3)

0= t2 sin 20 + t1 sin 40 - mg (4)

Solve (3)

0 = -t2 cos 20 + t1cos 40

t2 cos 20 = t1 cos 40

t2 = t1 cos40/cos20

t2 = 0.815 t1

Substitute t2 in 4

0 = t2 sin 20 + t1 sin 40 - mg

0 = (0.815 t1) sin 20 + t1 sin 40 - 8,820

0= t1 ( 0.815 sin 20 + sin 40 ) -8820

0 = 0.921 t1 -8820

8820 = .921 t1

t1 = 8820/0.921

If the force of gravity pulling down, the reaction force is the chair pushing up on the person.

option A is the correct answer.

Newton's third law of motion states that for every action, there is an equal and opposite reaction.

For instance, If an object A exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A.

If the force of gravity pulling down, the reaction force from the surface on which the object is resting will be acting upwards.

Thus, based on the Newton's third law of motion, we can conclude that when the force of gravity is acting downwards on an object the reaction force from the resting surface will be acting upwards.

Gas particles can change to solid particles if the temperature decreases.

The state of matter of a substance is determined by its temperature and pressure. When the temperature of a gas decreases, its particles lose kinetic energy and slow down. This decrease in kinetic energy leads to a decrease in the average speed of gas particles.

As the temperature continues to decrease, the particles lose energy and move closer together. At a certain temperature known as the condensation point or the freezing point, the gas particles no longer have enough energy to overcome the intermolecular forces holding them together.

At this point, the gas undergoes a phase transition and changes into a solid. The process of gas turning into a solid is called condensation or freezing, depending on the specific substance.

During condensation, the gas particles arrange themselves in a more orderly and structured manner, forming a solid. The transition from gas to solid involves the release of energy, known as heat of fusion.

In summary, when the temperature of a gas decreases below its condensation or freezing point, the gas particles lose energy, slow down, and eventually come together to form a solid.

The magnitude of the average force exerted by the block on the bullet during that time is 202,304.147m N (m stands for bullet mass)

We got some values here,

v = 439 m/s

t = 2.17 ms = 2.17 × \(10^{-3}\) s

First, we should find the acceleration of the car. We assume that final speed of bullet after impact is 0 m/s, so here we go

a = v/t

a = \(v_{1}\) - \(v_{0}\) / \(t_{1}\)  - \(t_{0}\)

a = 0 - 439 / 2.17 × \(10^{-3}\)  - 0

a = -439 / 2.17 × \(10^{-3}\)

a = -439,000 / 2.17

a = -202,304.147 m/\(s^{2}\)

What actually happens when the result is negative is not the acceleration after the bullet hits the target, but the deceleration.

Now we got the amount of deceleration. We can found the force by the formula of: F = m.a but in the question there is no mass value of the bullet. So, we can answer this question by this way (we can ignore negative values)

F = m.a

F = m × 202,304.147 m/\(s^{2}\)

F = 202,304.147m N

Acceleration (a) is the change of velocity (Δv) over the change of time (Δt), and here is the formula, a = Δv/Δt. This formula allows you to measure how quick velocity changes in meters per second squared (m/s. Acceleration is also a vector quantity, so it includes both magnitude and direction.

As we are unaware of the details of their rotation, we cannot determine if the batons have the same moment of inertia. The correct answer is an option (c) "Cannot determine."

When it comes to the rotational motion of objects, the moment of inertia is a significant physical property. The moment of inertia refers to an object's resistance to rotation. It is determined by the object's mass distribution and shape.

It is denoted by "I." When a body of mass "m" is rotated about a perpendicular axis at a distance "r," the moment of inertia is expressed as "I = mr²." The moment of inertia of a uniform rod about its end is "mL²/3," where "m" is the rod's mass, and "L" is the rod's length.

As a result, the moment of inertia is influenced by an object's mass distribution and shape. As a result, we can't determine whether two batons have the same moment of inertia without knowing the specifics of their rotation.

"The force that can cause an object to rotate along an axis is measured as torque." Similar to how force accelerates an object in linear kinematics, torque accelerates a body in an angular direction.

Torque is a measure of the turning effect of an applied force about a specific point or axis. It is computed by multiplying the force exerted on a body by the separation between the point of rotation and the application of the force.

The torque increases as the force or distance from the centre of rotation increases. The unit of torque is typically Newton-meters (N·m) in the International System of Units (SI) or pound-feet (lb·ft) in the imperial system. In several fields, including physics, mechanics, engineering, and robotics, torque is important.

Yes, friction plays a role. Yes, I believe that proven conservation of energy and conservation of work-kinetic energy and the work-kinetic energy theorem.

The work-energy theorem, or the work-kinetic energy theorem, as I prefer to call it, says

Wnet=ΔK

Where K is kinetic energy and W represents work.

We require a comprehensive summation of all forces acting on an object, whether positive or negative, to obtain a reliable value for Wnet. Whatever is left after subtracting the losses (negative work such as friction) and any positive work done by the motive forces is given as the change in kinetic energy of the object.

Overall, energy is saved. According to this theorem, when an object slows down, its final kinetic energy is less than its initial kinetic energy, the change in its kinetic energy is negative, and so is the net work done on it. If an object accelerates, the net work done on it is positive. When calculating the mesh, you must include all the forces acting on the object.

If you omit any forces that act on the object, or if you include any forces that do not act on it, you will get the wrong result. The importance of the work-energy theorem, and the other generalizations it leads to, is that some types of calculations are much simpler than trying to solve Newton's second law.

The wolf's kinetic energy is 2,500 joules, calculated using the formula KE = 0.5 × mass × velocity².

The kinetic energy of an object is the energy it possesses due to its motion.

It can be calculated using the formula KE = 0.5 × mass × velocity², where KE represents kinetic energy, mass is the object's mass in kilograms, and velocity is its speed in meters per second.

In this case, the mass of the wolf is 50 kg, and its velocity is 10 m/s.

Plugging these values into the formula, we get KE = 0.5 × 50 × (10)², which simplifies to KE = 0.5 × 50 × 100.
