A ball A moving with certain velocity collides with another body B of the same mass at rest. If the coefficient of restitution is 2/3. The ratio of velocity of A and B after collision is

A ball A moving with a certain velocity collides, with another ball B of the same mass at rest. If the coefficient of restitution is e, the ratio of the velocities of A and B just after the collision is

A ball P is moving with a certain velocity v , collides head-on with another ball Q of same mass at rest. The coefficient of restitution is 1/4, then ratio of velocity of P and Q just after the collision is

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

A block of mass m moving at a velocity upsilon collides head on with another block of mass 2m at rest. If the coefficient of restitution is 1/2, find the velocities of the blocks after the collision.
