A ball orf mass 100 g dropped on the ground from 5 m bounces repeatedly. During every bounce 64% of the potential energy is converted into kinetic energy. Calculate the following:
(a) Coefficient of restitution
(b) Speed with which the ball comes up from the ground after third bounce.
(c) Impulse given by the ball to the ground during this bounce.
(d) Average force exerted by the ground if the impact lasts for 250ms.​

From the terrace of building of height H, you dropped a ball of mass m. It reached the ground with speed v. Is the relation mgH = frac(1)(2)mv^2 applicable exactly ? If not, how can you account for the difference ? Will the ball bounce to the same height from where it was dropped?

A ball is thrown vertically downwards from a height of 20m with an intial velocity v_(0) . It collides with the ground, loses 50% of its energy in collision and rebounds to the same height. The intial velocity v_(0) is (Take, g =10 ms^(-2) )
