The pulley shown (Figure 1) has a moment of inertia IA = 0.625 kg⋅m2 , a radius r = 0.250 m , and a mass of 20.0 kg. A cylinder is attached to a cord that is wrapped around the pulley. Neglecting bearing friction and the cord’s mass, express the pulley’s final angular velocity in terms of the magnitude of the cord’s tension, T (measured in N), 4.00 s after the system is released from rest. Use the principle of angular impulse and momentum.
