Two 30 kg blocks rest on a massless belt which passes over a fixed pulley and is attached to a 40 kg block. If coefficient of friction between the belt and the  table as well as between the belt and the blocks B and C is `mu` and the system is released from rest from the position shown, the speed with which the block B falls off the belt is
