A 65-N weight is released from rest and falls to the floor as shown in the figure. It is suspended by a string of negligible mass that is wrapped around a 5.0 kg pulley that is essentially a solid disk of a radius of 1.75 m and rotates through 5.5 radians. What is the angular speed of the pulley? (Note: Since the pulley has mass, the sum total of the forces acting on the pulley is not simply the weight of the suspended object. You need to think about the tension in the string as well. An alternative approach would be to use conservation of energy.)

A weight of mass 1.66 kg is suspended by a string wrapped around a pulley wheel, which consists of a solid disk of mass 4.03 kg and radius 0.603 m. The system is released from rest. Over what vertical distance does the hanging mass move in 3.0 seconds? Ignore friction and drag forces, and assume that the string does not slip.

A 150-g weight is tied to a piece of thread wrapped around a spool, which is suspended in such a way that it can rotate freely. When the weight is released, it accelerates toward the floor as the thread unwinds. Assume that the spool can be treated as a uniform solid cylinder of radius R 3 cm and mass Ms 100 g. Find the tension in the thread and the magnitude of the acceleration of the weight as it descends....
