A 75 kg woman stands on the edge of a horizontal turntable. The moment of inertia of the turntable is 750 kg.m2 and the radius is 3.5 m. The turntable, which is initially stationary, can rotate freely about the frictionless vertical axis passing through its center. The woman starts walking clockwise (when viewed from above) along the edge of the table at a constant speed of 0.50 m/s with respect to the ground. How much work did the woman do to make herself and the turntable movable? A) 99.90 J B) 20.86 J C) 64.00 J D) 43.65 J E) 65.40 J
