A ball is let fall from a height `h_(0)`. There are `n` collisions with the earth. If the velocity of rebound after `n` collisions is `v_(n)` and the ball rises to a height `h_(n)` then coefficient of restitution `e` is given by

A ball is let fall from a height h. It makes n collisions with the earth. After n collisions it rebounds with a velocity v_(n) and the ball rises to a height h_(n) then coefficient of restitution is given by

A ball is let to fall frm a height h_(0) . It makes 'n' collisions with the horizontal ground. If after 'n' collisions it rebounds with a velocity v_(n) and the ball rises to a height h_(n) , then the coefficient of restitution for the collision is

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

A body is allowed to fall on the ground from a height h_(1) . If it is rebound to a height h_(2) then the coefficient of restitution is:

A body is allowed to fall on the ground from a height h_1 . If it is to rebound to a height h_2 ,then the coefficient of restitution is
