NEXT Chapter 10, Problem 066 GO A uniform spherical shell of mass M = 12.0 kg and radius R = 0.710 m can rotate about a vertical axis on frictionless bearings (see the figure). A massless cord passes around the equator of the shell, over a pulley of rotational inertia I = 0.0980 kg-m2 and radius r = 0.140 m, and is attached to a small object of massm = 4.80 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 a distance 1.00 m after being released from rest?

The rotor of an electric motor has rotational inertia Im about its central axis. The motor is used to change the orientation of the space probe in which it is mounted. The motor axis is mounted along the central axis of the probe; the probe has rotational inertia I, about this axis. Calculate the number of revolutions of the rotor required to turn the probe through angle e (measured in radians) about its central axis. State your answer in terms of the given variables, using TT when appropriate.

A homogeneous pulley with two grooves consists of two wheels which turn together as one around the same axis. The moment of inertia of the two wheels together is ICM = 40 kg m2. The radii are: R1 = 1.2 m and R2 = 0.4 m. The masses that hang on both sides of the pulley are m1 = 36 kg and m2 = 12 kg. We will assume that the masses of the ropes are negligible. Determine the angular acceleration of the pulley, acceleration of the masses, and the tensions of the ropes.
