6. A pulley of moment of inertia 2.0 kg m is mounted on a wall as shown in the following figure. Light strings are wrapped around two circumferences of the

pulley and weights are attached. Assume the following data: rl = 50 cm, r2 = 20 cm, m1 = 1.0 kg, m2 = 2.0 kg.What are [6 pt] a. the angular acceleration of the pulley, and b. the linear acceleration of the weights?
