A body is hanging from a rigid support by an inextensible string of length l. It is struck inelastically by an identical body of mass m moving with horizontal velocity v = root 2 gl the tension in the string increases just after striking by

A glass ball collides with a smooth horizontal surface (xz plane) with a velocity V=ai-bj. If the coefficient of restitution of collision be e the velocity of the ball just after the collision will be
