Question

A 60.0-kg woman stands at the rim of a horizontal
turntable having a moment of inertia of 500 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 Earth. (a) In what direction and with
what angular speed does the turntable rotate? (b) How much
work does the woman do to set herself and the turntable
into motion?
