Auniform spherical shell of mass = 4.50 kg and radius = 8.50 cm can rotate about a vertical axis on frictionless bearings. a massless cord passes around the equator of the shell, over a pulley of rotational inertia = 3.00 × 10−3 kg ∙ m2 and radius = 5.00 cm, and is attached to a small object of mass m = 0.600 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 82.0 cm after being released from rest? use energy considerations.
