A ball of mass `m` collides with the ground at an angle. With the vertical. If the collision lasts for time `t`, the average force exerted by the ground on the ball is : (e = coefficient of restitution between the ball and the ground)
.

A rubber ball is dropped on the ground from a height of 1m. What is the height to which the ball will rebound, if the coefficient of restitution between the ball and the ground is 0.8?

A ball hits the ground and loses 20 % of its momentum. Coefficient of restitution is

A ball is projected from the ground with speed u at an angle alpha with horizontal. It collides with a wall at some distance from the point of projection and returns on the same level. Coefficient of restitution between the ball and the wall is e, then time taken in path AB and maximum height attained by the ball is

After falling from a height h and striking the ground twice, a ball rise up to the height [e = coefficient of restitution]

A ball is dropped from height 5m. The time after which ball stops rebounding if coefficient of restitution between ball and ground e=1//2 , is

A ball is dropped from height 5m. The time after which ball stops rebounding if coefficient of restitution between ball and ground e=1//2 , is
