1.	A ball is dropped from a height h on to a floor. If in each collision its speed becomes e times of its striking value, then total change in momentum of ball when it stops rebounding is (Here, e is coefficient of restitution between the ball and the floor)
Answer» A ball is dropped from a height $h$ on to a floor. If in each collision its speed becomes $e$ times of its striking value, then total change in momentum of ball when it stops rebounding is (Here, $e$ is coefficient of restitution between the ball and the floor)
