A ball is dropped from a height of `125m`. After first collision with ground ball reaches to maximum height `100m` .If maximum heights achieved by the ball after `2^(nd)` and `4^(th)` collision are `h_(2)` and `h_(4)` respectively then calculate `(h_(2)/h_(4))`

A steel ball is dropped on a hard surface from a height of 1m and rebounds to a height of 64cm . The maximum height attained by the ball after n^(th) bounce is (in m)

A ball is dropped from a height h on to a floor . If the cofficient of restitution is e, calculate the height the ball first rebounds ?

A ball is dropped from a height of 20 m in the floor and rebounds to 1.25 m after second collision, then coefficient of restitution e is

A ball dropped from a height of 2 m rebounds to a height of 1.5 m after hitting the ground. Then fraction of energy lost is

A ball is dropped from a height of 10 m. If the energy of the ball reduces by 40% after striking the ground, how much high can the ball bounce back ? (g = 10m//s^2)

A small metallic spherical ball is dropped from a height h . If it collides with the ground inelastically and rebounds, then

Two balls of same mass are dropped from the same height h, on to the floor. The first ball bounces to a height h//4 , after the collision & the second ball to a height h//16 . The impulse applied by the first & second ball on the floor are I_(1) and I_(2) respectively. Then :-

A ball is dropped from a height h on a floor. The coefficient of restitution for the collision between the ball and the floor is e. The total distance covered by the ball before it comes to the rest.

A ball is thrown up at a speed of 4.0 m/s. Find the maximum height reached by the ball. Take g=10 m//s^2 .

A body is thrown vertically up reaches a maximum height of 78.4 m. After what time it will reach the ground from the maximum height reached ?
