A tennis ball bounces down a flight of stairs, striking each step in turn and rebounding to half to height of the step. The coefficient of restitution is

A ball falls from a height 20m on to a horizontal plane and rebound to a height of 5/64m after 4 collisions.Find the coefficient of restitution.

A ball falls on the ground fro a height of 2.0 m and rebounds up to a height of 1.5 m. Find the 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 ball is dropped from a height h onto a floor and rebounds to a height h//6 . The coefficient of restitution between the ball and the floor is

A ball falls from rest from a height h onto a floor, and rebounds to a height h//4 . The coefficient of restitution between the ball and the floor is

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

A 1.0 kg ball drops vertically into a floor from a height of 25 cm . It rebounds to a height of 4 cm. The coefficient of restitution for the collision is

A body dropped freely from a height h onto a horizontal plane, bounces up and down and a horizontal plane, bounces up and down and finally comes to rest. The coefficient of restitution is e . The ratio of velocities at the beginning and after two rebounds is

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
