A 60.0 kg woman stands at the rim of a horizontal turntablehaving a moment of inertia of 500 kgm^2 and a radius of 2.00m. The turntable is initially at rest and is free to rotateabout a frictionless, vertical axle through its center. Thewoman then starts walking around the rim clockwise (as viewed fromabove the system) at a constant speed of 1.50 m/s relative to theEarth.
a) In what direction and with what angular speed does theturntable rotate?
b) How much work does the woman do to set herself and theturntable into motion?
