Chapter 10, Problem 66P
GO A uniform spherical shell of mass M = 4.5 kg and radius R = 8.5 cm can relate about a vertical axis on frictionless bearings (Fig. 10-47). A massless cord passes around the equator of the shell, over a pulley of rotational inertia I = 3.0 × 10−3 kg·m2 and radius r = 5.0 cm, and is attached to a small object of mass m = 0.60 kg. There is no friction on the pulley's axle; the cord does not slip on the pulley. What is the speed of the object when it has fallen 82 cm after being released from rest? Use energy considerations.
