A stick of length `l` lies on horizontal table. It has a mass `M` and is free to move in any way on the table. A ball of mass `m` moving perpendicularly to the stick at a distance d from its centre with speed `v` collides elastically with it as shown in figure. What quantities are conserved in the collision ? what must be the mass of the ball, so that it remains at rest immediately after collision?
