Two particles of masses m1 and m2 and velocities u1 and αu1 ( α≠0) make an elastic head on collision. If the initial kinetic energies of the two particles are equal and m1 comes to rest after collision, then

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
