Two masses are attached to strings wound around a double pulley as shown. The double pulley has a total mass of 1200g (1.2kg), and the total moment of inertia about its center is 50,000g·cm2(0.005kg·m2).
(a) If the pulley is released from rest, which direction will it rotate?
(b) Calculate the angular acceleration of the double pulley.
(c) Which mass is traveling faster at any instant?
(d) Calculate the velocity of the 300g mass at t = 2s.
