Academics

A woman with mass of 55 kg stands at the rim of a horizontal table having a moment of inertia of 410 kg m2 and a radius of 1.6 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 of1.1 m/s relative to the Earth. (1st question) With what angular speed does the turntable rotate? Answer in units of rad/s (2nd question) How much work does the woman do ON THE TABLE to set it into motion?

Answer in units of J
