A ball of mass in collides horizontally with a stationary wedge on a rough horizontal surface, in the two orientations as shown. Neglect friction between the ball and the wedge. The students comment on the system of ball and wedge in these situations Saurav: Momentum of the system in x -direction will change by significant amount in both the cases. Rahul: There are no impulsive external forces in x -direction in both cases, hence the total momentum of the system in x -direction can be treated as conserved in both cases.

A plank of mass m rests symmetrically on two wedges B and C of mass M. What is the acceleration of the plank? Neglect friction between all the contact surfaces.

A horizontal force F pushes wedge of mass M on a smooth horizontal surface. A block of mass m is stationary to the wedge, then:

A block of mass m is placed at rest on a smooth wedge of mass M placed at rest on a smooth horizontal surface. As the system is released

A block of mass m rests on a stationary wedge of mass M. The wedge can slide freely on a smooth horizontal surface as shown in figure. If the block starts from rest
