Question

We wrap a light, non- stretching cable around a solid cylinder, of mass 50 kg and radius 0.060 m. The cylinder rotates in frictionless bearings about a stationary horizontal axis. We pull the free end of the cable with a constant 9.0-N force for a distance of 2.0 m; it turns the cylinder as it unwinds without slipping. The cylinder is initially at rest. a) (3 pts) What is the moment of inertia of the cylinder? b) (7 pts) Calculate the final angular speed of the cylinder. c) (4 pts) We do the exact same experiment again, but now with a different force. We note that the final angular speed is now two times larger. What force did we use? PART II: 15 MULTIPLE-CHOICE QUESTIONS, FOR 4 POINTS EACH; TOTAL 60 POINTS Do not
