A small 600 g ball on the end of athin, light rod is rotated in a horizontal circle of radius1.6 m.

(a) Calculate the moment of inertia of the ball aboutthe center of the circle.

kgm2

(b) Calculate the torque needed to keep the ball rotating atconstant angular velocity if air resistance exerts a force of0.030 N on the ball. Ignore the rod'smoment of inertia and air resistance.
