Statement-1 : A body with negative energy cannot have momentum. Statement-2 : This is because momentum can be positive only.

Two blocks of masses 2m and m are connected by a light string going over a pulley of mass 2m and radius R as shown in the figure. The system is released from rest. Find the angular momentum of system when the mass 2m has descended through a height h . Assume no slipping.
