A mass is connected to a pulley of radius R and mass as shown in Figure P9.74. The mass starts from rest and then falls through a distance h. (a) Use conservation of energy to calculate the linear speed of (b) What is the final angular velocity of the pulley? (c) What is the final angular momentum of the pulley? (d) What was the source of the torque that produced this angular momentum?
