A block A on a smooth inclined plane is connected to block B as shown in the figure using an inextensible cord which pass over a mass-less and friction-less pulley. Initially, the block B is constrained to be at rest. If the constraint on block B is released, the magnitude of velocity (in m/s) of the block ‘B’ after 2 seconds from its release is __________ (assume g =10 m/s2). 200 N 30o O 100 N 50 N-m 2 m 2 m 50 N 4 m A 1 m A B 30º 10 kg 5 kg
