500 N 20 kg A B 10 kg 600 mm C SB Figure 9: A pulley system with weights 9. The system shown in Fig. 9 consisting of a 20-kg collar A and a 10-kg counterweight B, is at rest when the 500-N force is applied to the collar A. Neglect friction, and the pulleys are massless. Answer the following questions. (a) What is the work done by the 500-N force when the collar A travels to point C? (b) Let SA and SB be the position of collar A and counterweight B from the fixed pulley. How much does counterweight B move up when collar A travels to the point C? How is the velocity VA of collar A related to the velocity vB of the counterweight B? (c) Use point C as the datum plane. What is the change of the gravitational potential energy AV of the entire system when the collar A moves to point C? Initially collar A and counterweight B are at the same level as shown. (d) What is the velocity of collar A immediately before it hits point C?
