Blocks A and B have masses of 11 kg and 5 kg, respectively, and they are both at a height h = 2 m above the ground when the system is released from rest. Just before hitting the ground, Block A is moving at a speed of 3 m/s. Determine (a) the amount of energy dissipated in friction by the pulley, (b) the tension in each portion of the cord during the motion.
