A 65.0-kg woman stands at the rim of a horizontal turntable having a moment of inertia of 460 kg · m2 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? clockwise or 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? Incorrect: Your answer is incorrect. Calculate the work done using the final energies and the work-energy theorem. J
