A stick of length L and mass M lies on a frictionless horizontal surface on which it is free to move in any way. A ball of mass m moving with speed v collides elastically with the stick as shown in fig. If after the collision ball comes to rest, then what should be the mass of the ball?
(a) m = 2 M
(b) m = M
(c) m = M/2
(d) m = M/4
