A sphere `A` impinges directly on an identical sphere `B` at rest. If coefficient of restitution is `e` , the ratio of velocities of `A` and `B` after collision is

A sphere of mass m moving with a uniform velocity v hits another identical sphere at rest. If the coefficient of restitution is e, the ratio of the velocities of the two sphere after the collision is (e-1)/(e+1) .

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 spherical body collision head-on with another identical spherical body at rest. If the coefficient of restitution is e, show that the ratio of their velocities after collision is (1-e):(1+e) .

A particle of mass m moving with a constant velocity v hits another identical stationary particle. If coefficient of restitution is e then ratio of velocities of two particles after collision is

A particle of mass m moving with a constant velocity v hits another identical stationary particle. If coefficient of restitution is e then ratio of velocities of two particles after collision is
