4) The double pulley shown has a mass of 150 mm 15 kg and a centroidal radius of gyration of 160 mm. Cylinder A and block B are attached to cords that are wrapped on the pulleys as shown. The coefficient of kinetic friction between block B and the surface is Hk = 0.2. Knowing that the system is at rest in the position shown when a constant force P = 200 N is applied to cylinder A, 250 mm 30° 5 kg 15 kg determine a) the velocity of cylinder A as it strikes the ground, b) the total distance that block B moves before coming to rest.
