A thin-walled hollow sphere with radius R = 0.050 m is released from rest at the top of an incline, a vertical distance of 2.0 m above the bottom of the incline. The moment of inertia of the sphere about the rotation axis through its center is (2/3) mR2. There is sufficient friction for the sphere to roll without slipping. What is the angular velocity of rotation of the sphere when it gets to the bottom of the incline?
