Two cylinders A and B, having a weight of 10 lb and 5 lb, respectively, are attached to the ends of a cord which passes over a 3-lb pulley (disk). If the cylinders are released from rest, determine their speed in t = 0.5 s. The cord does not slip on the pulley. Neglect the mass of the cord. Analyze the “system” consisting of both the cylinders and the pulley.
