A woman with mass of 58 kg stands at the rim of a horizontal table having a moment of inertia of 430 kgm2 and a radius of 2.1 m. The turntable is initially at rest and is free to rotate about a frictionless, vertical axis through its center. The woman then starts walking around the rim clockwise (as viewed from above the system) at a constant speed of 1.3 m/s relative to the Earth. With what angular speed does the turntable rotate?
