A ball of mass m moving with velocity u strikes another identical ball at rest. Find the velocities of the balls after the collision if the coefficient of restitution is e and the collision is head -on. Also , calculate the loss in K.E.

Ball 1 collides with another identical ball at rest. For what value of coefficient of restitution e, the velocity of second ball becomes two times that of 1 after collision? _____.

Two balls of masses 2 m and m are moving with speed 2 v_(0) and v_(0) towards each other. If the coefficient of restitution e = 1//3 , the speed of balls , if collision is head - on

N identical balls are placed on a smooth horizontal surface. An another ball of same mass collides elastically with velocity u with first ball of N balls. A process of collision is thus started in which first ball collides with second ball and the with the third ball and so on. The coefficient of restitution for each collision is e . Find the speed of Nth ball.

The first ball of mass m moving with the velocity upsilon collides head on with the second ball of mass m at rest. If the coefficient of restitution is e , then the ratio of the velocities of the first and the second ball after the collision is
