Find with what angularspeed does the turntable rotate

Reference no: EM13652129

A 65.0 kg woman stands at the rim of ahorizontal turntable having a moment of inertia of 485 kg·m2 and a radius of 2.00 m.The turntable is initially at rest and is free to rotate about africtionless, vertical axle through its center. The woman thenstarts walking around the rim counterclockwise (as viewed fromabove the system) at a constant speed of 1.50 m/s relative to theEarth.

(a) In what direction and with what angularspeed does the turntable rotate?

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