A small 460-gram ball on the end of a thin, light rod is rotated in a horizontal circle of radius 1.1 m .

Part A

Calculate the moment of inertia of the ball about the center of the circle.

Part B

Calculate the torque needed to keep the ball rotating at constant angular velocity if air resistance exerts a force of 0.021 N on the ball. Ignore air resistance on the rod and its moment of inertia.
