A ball of mass m moving at speed v makes a head on collision with an identical ball at rest. The kinetic energy of the balls is three fourth of the original kinetic energy. The coefficient of restitution is.

A sphere of mass m moving with a constant velocity u hits another stationary sphere of the same mass and of coefficient of restitution (e). The ratio of velocities of the two spheres after collision will be
