A pulley with a radius of 14.0 cm is mounted on an axle that passes through the center of the pulley. The axle allows the pulley to rotate with negligible friction. The pulley is initially at rest. At t = 0, you start pulling on the end of a string that is wrapped around the outside of the pulley, giving the pulley a constant angular acceleration of 3.00 rad/s2. After t = 5.00 s of you pulling on the string, calculate the following. (a) the instantaneous angular speed of the pulley rad/s (b) the instantaneous speed of a point on the edge of the pulley m/s (c) the number of revolutions the pulley has made (this does not have to be an integer) revolutions

A thin rod has a length of 0.792 m and rotates in a circle on a frictionless tabletop. The axis is perpendicular to the length of the rod at one of its ends. The rod has an angular velocity of 0.939 rad/s and a moment of inertia of 1.41 x 103 kg-m². A bug standing on the axis decides to crawl out to the other end of the rod. When the bug (whose mass is 5 x 10-³ kg) gets where it's going, what is the change in the angular velocity of the rod?
A circular disk with a radius of 0.38 m is subject to 2 tangentially applied forces. The disc is fixed such that it will rotate about its center. Both forces produce a torque in the same direction. The mass of the disc is 0.73 kg. The moment of inertia of a disc is I =1/2MR^2 F1 = 2.3 N applied at the outer edge of the disc. F2 = 3.6 N applied at a distance of 0.29 from the center of the disc. What is the angular acceleration of the disc?
A capstan is a device used on old sailing ships to raise the anchor. A sailor pushes the long lever, turning the capstan and winding up the anchor rope. If the capstan turns at a constant speed, the net torque on it, is zero. The rope tension due to the weight of the anchor is 1500 N. The distance from the axis to the point on the lever where the sailor pushes is seven times the radius of the capstan around which the rope is wound.With what force must the sailor push in order to turn the capstan at a constant speed, meaning that the net torque on the capstan is zero?
A customer service person in a department store is wrapping packages for customers. The ribbon spool she uses has 13.7 m of ribbon wound on it. The radius of the spool is 16.0 cm and its moment of inertia is 0.55 kg. m². As the spool turns, friction forces cause a torque of 0.17 N m to act on it. The spool is initially at rest. The service person pulls on the spool with a constant tension of 11.5 N. Determine the time it takes, in seconds, to unwind 5.5 m of the ribbon, assuming there is no slippage and the mass of the ribbon is negligible.
