I have tried this problem many times, but I can't even get it started really. Any hints are appreciated!
A 60.0 kg woman stands at the rim of a horizontal turntable having a moment of inertia of 500kg/m^2 and a radius of 2 meters. 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 (birdseye view) at a constant speed of 1.5m/s relative to earth.
(a) In what direction and with what speed does the turntable rotate?
(b) How much work does the woman do to set herself and the turntable into motion?
Thanks
Josh
