A sphere of mass `m`, impinges obliquely on a sphere, of mass M, which is at rest. Show that, if `m=eM`, the directions of motion of the sphere after impact are at right angles.

The escape velocity of a sphere of mass m is given by

A sphere of mass 'm' moving with velocity 'v' collides head-on on another sphere of same mass which is at rest. The ratio of final velocity of second sphere to the initial velocity of the first sphere is (e is coefficient of restitution and collision is inelastic)

A ball of mass 2m impinges directly on a ball of mass m, which is at rest. If the velocity with which the larger ball impringes be equal to the velocity of the smaller mass after impact then the coefficient of restitution :-
