6 A series of n elastic balls whose masses are m em e m etc are at rest separated by intervals with their centres on a straight line Here e is coefficient of restitution for the collision The first is made to impinge directly on the second with velocity u Then 1 The first n 1 balls will be moving with the same velocity 1 e u 2 The last one ball will move with velocity u 3 The kinetic energy of the system is mu 1 e e 4 None of these
