A body falling from a height of 10 m rebounds .from a hard floor. It loses 20% of its energy in impact. What is the height to which it would rise after the .impact?

A ball is dropped from a height of 20m. it rebounds to a height on 10m. Calculate the loss of energy of the ball

An elastic ball is dropped from a height to 100m.It lose s 20% of its energy .To what height will the ball rebound?

A body falling from a height travels 40 m in the last 2s of its fall to ground. The height in meter is

A ball is dropped from rest at a height 12m.If is loses 25% of its kinetic engeryt of striking the ground,Calculate the height to which it bounces.

A ball falls under gravity from a height of 10m with an initial velocity. It collides with the ground,loses 50% of its engery and then rises to the same height.Find the initial velocity.

A body is allowed to fall from a height of 20 metres from the ground. How much time will take to reach the ground? What will be its velocity just a moment before hitting the ground?

A ball is dropped from a height of 90 m on a floor. At each collision with the floor, the ball loses one tenth of its speed. Plot the speed time graph of its motion between t = 0 to 12 s.

. A lead ball falling freely from a height strikes the ground, As a results, its temperature rises. This is due to

A rain drop of radius 2 mm falls from a height of 500 m above the ground. It falls with decreasing acceleration (due to viscous resistance of the air) until at half its original height, it attains its maximum (terminal) speed, and moves with uniform speed thereafter. What is the work done by the gravitational force on the drop in the first and second half of its journey? What is the work done by the resistive force in the entire journey if its speed on reaching the ground is 10 m s-^1 ?

A stone falls from the top of a building and travels 53.9 m in the last second before it reaches the ground. Find the height of the building.
