What is the motion of a ball dropped from a height?

Answer: uniform acceleration is the correct answer.

How high does the ball rebound?

The Synthetic Turf Council (STC) and FIFA recommend that a soccer ball rebounds to a height between 60 to 100 centimeters on a community field, and 60 to 85 centimeters on a stadium field.

What is the formula for rebound velocity?

v ^2 = 2gh. Square of the ground velocity is proportional to height from which it is dropped. Time between first and second bounce is 2*1.515 = 3.03 s.

How do you measure a rebound ball?

Just using these two measurements, I can find the rebound ratio. Using the geometric sequence formula, we have 111=200(r)(2−1). 200 represents the initial height, and (2, 111) represents the second height after the first bounce at 111 cm. We now know that this ball has a 55.5\% rebound ratio.

What is a rebound in physics?

Occasionally when objects collide, they bounce off each other as opposed to sticking to each other and traveling with the same speed after the collision. Bouncing off each other is known as rebounding. Rebounding involves a change in the direction of an object; the before- and after-collision direction is different.

What is the speed of the ball when it hits the floor?

Since the ball falls from a height of 5m, its speed at the time of striking the concrete floor, can be obtained using the relation v² – u² = 2 g h. In our case u = 0 m/s as it is just dropped; h = 5 m; g = 10 m/s². So v² = 2× 10×5 = 100 (m/s)² or v = 10 m/s.

When a ball is dropped from a height of 10m?

Originally Answered: A ball is dropped from a height of 10m . it loses 10 \% of its initial energy due to air resistance and 10\% when the ball comes in contact with th e ground. till what height will the ball bounce back again? The ball falling from the height of 10 meters, means initially it is having 100 percent of energy due to its height.

What is the average acceleration of a basketball when it is dropped?

A ball is dropped on the floor from a height of 10 m. It rebounds to a height of 2.5 m.If the ball is in contact with the floor for 0.01 sec, then average acceleration during contact is  A 2100m/s2

How long does it take for a basketball to hit the ground?

So it takes approximately 3 seconds for the ball to reach the surface of the earth (neglecting air resistance). A ball is dropped from a height of 5m onto a concrete floor and rebounds with a speed of 0.8 times the down ward speed on arrival.
