KHw-set#7-chapter17-probs Problem 17.78 Two cylinders A and B, having a weight of 8 lb and 4 lb, respectively, are attached to the ends of a cord which passes over a 3-lb pulley (disk). The cylinders are released from rest. The cord does not slip on the pulley. Neglect the mass of the cord. Suggestion: Analyze the system consisting of both the cylinders and the pulley. (Figure 1) Part A Determine their speed in t 0.5. Express your answer to three...

The figure shows two blocks connected by a cord (of negligible mass) that passes over a frictionless pulley (also of negligible mass). The arrangement is known as Atwood's machine. Block 1 has mass m - 1.2 kg; block 2 has mass m2 = 2.7 kg. What are (a) the magnitude of the blocks'acceleration and (b) the tension in the cord? (a) Number Units (b) Number Units
