(a) What is the work done on the pulley by the cable? Are there any other forces that dowork?(b) What is the gain in kinetic energy due to the force and the angular speed of the pulleyafter being pulled 2.5 m?(c) What torque does the force apply to the pulley.(d) What is the angular acceleration of the pulley?(e) What is the angular displacement of the pulley as a result of being pulled by the forcefor 2.5 m?(f) How much time does it take to reach this angular displacement?(g) What is the angular speed after this time?

3) A light non-sketching cable is wrapped around a solid cylinder of mass 60 kg and diameter of 0.2 m. The pulley rotates on frictionless 2 5 m 15 N ' bearings about a stationary horizontal axis, 50 as shown in the gure. The free end of the u I 0-2 "" cable is pulled with a constant 15 N force for a distance of 2.5 m
