Nov 22, 2007 · A superball is dropped from a height, h, onto a hard steel plate (fixed to the Earth), from which it rebounds at very nearly its original speed. The ball starts from a certain height above the ground, elastically collides with the ground, rebounds with the same speed it hit the ground, then reaches the point of dropping. This process constitutes one cycle. The change in momentum of the ball in one cycle is therefore zero, as both the initial and final velocities are same (equal to zero here).

We can determine the percentage of speed that the ball retains after the collision by use of the coefficient of restitution, Where, V after and V before are the speeds before and after the collision. The larger this parameter is, the more elastic the collision, i.e. the fewer the energy losses. Furthermore, if we let a ball drop from a certain height, the height that it will reach after the rebound is higher for balls with a greater coefficient of restitution. positioned at a height above (or below) the zero height. An object possesses elastic potential energy if it is at a position on an elastic medium other than the equilibrium position. Check Your Understanding .

Suppose you drop a tennis ball from a height of 15 feet. After the ball hits the floor, it rebounds to 85% of its previous height. How high will the ball rebound after its third bounce? Round to the nearest tenth. A super ball is dropped from a height of 2 m and bounces 90% of its original height on each bounce. Ball loses 25% of (final K.E.), so initial energy with which it bounces back = 75% of (final K.E) = (3/4) × 120M = 90M. So to find the height to which the ball will bounce back we equate the initial energy (that is 90M) with the final energy (that is potential energy at the maximum height to which the ball has bounced). 90M = MgH H= 9 metres.
