In the system shown initially the block A of mass m is hanging at rest and the block B of mass 2m is on the ground The pulleys have negligible masses and negligible friction and the thread is extremely light and almost inextensible Acceleration due to gravity is g The free end of the thread is pulled upwards with a constant force When it acquires a speed u find speeds of both the blocks B
