A ball is dropped from a height of 10 feet.Each time it hits the ground, it bounces to 80% of it’s previous height. Find the total distance travelled by the ball? See explanation. Although the question is places in Physics, it can be answered using maths only.

**it begins to fall**. The falling ball has the kinetic energy due to its motion.

When a ball is dropped from a height its speed increases gradually?

When a ball is dropped from a height, its speed increases gradually. What is the force which causes this change in speed? All objects fall because of the earth’s gravity. The vertical rate is a constant 9.8 meters/second every second. The closer an object falls to the earth’s surface, it will be effected by the atmosphere’s density.

What is the energy change that takes place when a ball is dropped?

State the energy change that takes place when a ball is dropped from some height. State the energy change that takes place when a ball is dropped from some height. A ball a height has the potential energy due to its raised position. When the ball is dropped from that position, it begins to fall.

What is the potential energy of a falling ball?

A ball has a gravitational potential energy given by mgh, where m is mass, g is the acceleration due to gravity, and h is the height. When the ball falls, some of its gravitational potential energy is converted to other forms of energy, such as kinetic energy and rotational energy.

Which ball would bounce higher from the same height?

Which ball would bounce higher if dropped from the same height? Explanation: When all three balls are dropped from the same height, the rubber ball will bounce the highest because it has the greatest elasticity.

A ball of mass .5 kg is dropped from a height of 78.4 m. What is the time taken by the ball to hit the ground? Originally Answered: A ball of mass 5kg is dropped from a height of 78.4m. What is the time taken by the ball to reach the ground?

What is the height of the ball dropped from?

A ball is dropped from a height of 10 m. A ball of mass 200 g falls from a height of 5 m. What is its K.E. when it just reaches the ground? A ball dropped from a 2 0 m height loses 4 0 % of its energy on hitting the ground. Upto what height does the ball rebound? A ball is dropped from a height of 20 m and rebounds to a height of 10 m.

How much energy does a ball lose when it hits the ground?

A ball dropped from a 2 0 m height loses 4 0 % of its energy on hitting the ground. Upto what height does the ball rebound? A ball is dropped from a height of 20 m and rebounds to a height of 10 m. The loss of energy is

What is the initial velocity of a ball?

where, u is the initial speed of the ball and since the ball is dropped from a height, therefore, its initial velocity is zero, i.e., u = 0 m/s. Thus, the work done by the weight of the ball in 1 second after it has dropped is given as:

What is the kinetic energy of a ball just before reaching ground?

b) Now when it reaches the ground then it’s height will be 0 and thus potential energy will also be 0, Now according to law of conservation of energy it’s potential energy will convert into it’s kinetic energy, Therefore the kinetic energy of ball just before reaching the ground will be 500J.

What is the height of the ball dropped on the floor?

A tennis ball is dropped on the floor from a height of 10 m. It rebounds to a height of 5 m. The ball was in contact with the floor for 0.01 s. What was its average A tennis ball is dropped on the floor from a height of 10m. It rebounds to a height of 5m.

Is the acceleration of a ball high or low?

The acceleration is high, however. It’s value will depend on the coefficients of restitution of the ball and the surface it bounces from. Considering your velocity-time graph, you start with an apparently positive acceleration, a straight line as the ball hits the floor, then a negative acceleration.

At 10m, the ball is just dropped… so it is stationary, so it’s kinetic energy is zero. (Gravitational) Potential energy is arbitrary… so you can set to to zero at 10m height if you like. Thus PE = 0 too. However, people setting these questions like you to choose the floor as PE=0 so all your potential energy numbers come out positive.

What happens to the kinetic energy of a dropped ball?

newtonian mechanics – What happens to the kinetic energy of a dropped ball when it comes to rest on the ground? – Physics Stack Exchange If we want to drop a ball from a height, we calculated that potential energy at bottom is zero and we say it is converted into kinetic energy. At that movement, if it is a kind of sand, we find it will be at rest.

What happens when a ball is dropped from a height?

A ball is dropped from a height of 10 m. (a) Its potential energy increases and kinetic energy – Brainly.in A ball is dropped from a height of 10 m. (a) Its potential energy increases and kinetic energy decreases during the falls.

What is the kinetic energy of 10 kg?

For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s 2.

Why does a ball have a systematic macroscopic kinetic energy?

Just before the ball reaches the ground, all of its molecules are coming down with almost an equal speed that is the speed of the ball. (Although, due to the non-zero temperature of the ball, the molecules are also vibrating about their mean position wrt COM frame of the ball).And thus the ball possesses a systematic macroscopic kinetic energy.
