A massless cord passes around the equator of the shell, over a pulley of rotational inertia I = 2.00 × 10-3 kg m 2 and radius r = 4.00 cm, and is attached to a small object of mass m = 1.00 kg. There is no friction on the pulley’s axle; the cord does not slip on the pulley. The system is initially at rest. a) When the speed of the hanging mass is 1.00 m/s, what are the angular speeds of the sphere and pulley? The cord does not slip on the sphere or pulley, thus their
