4. (25 points)A block of mass M is suspended by a massless, unstretchable rope from the pulley as shown. The pulley rotates freely about a fixed horizontal axle. The rope moves around the pulley without slipping. The pulley has a moment of inertia about its center of I and a radius R. A constant force of magnitude P is applied to the pulley as shown at the known angle 0. What will be the acceleration of the block, assuming it moves down? If the hanging mass is released from rest at t = 0, what will be the angular velocity of the pulley as a function of time? = P M Free Body Diagrams (If appropriate). Law or Definition
