A 65 kg woman stands at the rim of a horizontal more in details physics?

[Jay]

A 65 kg woman stands at the rim of a horizontal turntable having a moment of inertia of 500 kg·m2 and a radius of 2.0 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 1.5 m/s relative to the Earth.
(a) In what direction and with what angular speed does the turntable rotate?
__________clockwise or __________counterclockwise

___________rad/s

(b) How much work does the woman do to set herself and the turntable into motion?
