##### Reference no: EM13299561

The block A has a mass of M and the cylinder B has a mass of m. The masses of the pulleys and the rope can be neglected. The slope angle is 20o.

The cylinder B is released from rest. Determine the speed of both masses (vA and vB) after B moves by h m. Also calculate the angular displacement for the pulley D. The diameter of the pulley D is 0.2 m. Neglect all friction.
