3. Two masses mi = 0.50 kg and m; = 1.20 kg are connected by a mass less string over a pulley of radius 0.20 m and rotational inertia I. The string does not slip over the pulley and heavier mass slides down and reached the ground in 1.5 s from a height of 1.00m starting from rest. a) Draw free body diagrams for the objects. b) Determine the angular acceleration of the pulley? c) What is the mass of the pulley? 2.00 m
