A 55.0-kg woman stands at the rim of a horizontal turntable having a moment of inertia of 460 kg . m and a radius of 2.00 m. The turntable is initially at rest and is free to rotate about a frictionless vertical axle through its center. The woman then starts walking around the rim clockwise (as viewed from above the system) at a constant speed of 1.50 m/s relative to the Earth. (a) In what direction does the turntable rotate? O clockwise O counterclockwise With what angular speed does the turntable rotate? rad/s (b) How much work does the woman do to set herself and the turntable into motion
