5) Watching and Weighting! (7 pts) A pulley is attached to a building so that it cannot move except for frictionlessly rotating around its central axle. The pulley has a mass of M = 440 kg and a radius ofR = 5.94 m. A rope is wrapped around the pulley and attached to a hanging mass of mass m = 2100.0 kg. The small mass is allowed to fall from rest. As it descends, the pulley spins as the rope unwinds from the pulley without slipping. The tension in the rope is T = 2100.0 N. What is the moment of inertia ofthe pulley? HINT: You do NOT know the exact shape or mass distribution of the pulley. This question cannot be answered by looking up a formula for moment of inertia. The answer is NOT Ipuuey z 7.760 kg m2
