A ball of mass 10 kg strikes another ball of mass 25 kg at rest. If they separated in mutually perpendicular directions then the coefficient of restitution is:

A ball of mass M strikes another smooth ball of mass m at rest. If they separate in mutually perpendicular directions, then the coefficient of impact (e) is :

A ball of mass m moving at a speed v collides with another ball of mass 3m at rest. The lighter block comes to rest after collisoin. The coefficient of restitution is

A ball of mass m moving at a speed v collides with another ball of mass 3m at rest. The lighter block comes to rest after collisoin. The coefficient of restitution is

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.

A ball of mass 2kg moving with speed 5m/s collides directly with another ball of mass 3kg moving in the same direction with speed 4m/s. The coefficient os restitution is 2/3. Find the velocities of both ball after the collision.
