A wedge of mass M = 2m rests on a smooth horizontal plane. A small block of mass m rests over it at left end A as shown in figure. A sharp impulse is applied on the block, due to which it starts moving to the right with velocity v_(0) = 6 ms^(-1) . At highest point of its trajectory, the block collides with a particle of same mass m moving vertically downwards with velocity v = 2 ms^(-1) and gets stuck with it.
