1. The problem statement, all variables and given/known data I'm not really sure what I'm supposed to be checking for in the following question: A 60.0kg woman stands at the western rim of a horizontal turntable having a moment of inertia of 500 kg m^2 and a radius of 2.00 m. 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 (as viewed from above the system) at a constant speed of 1.5m/s relative to the Earth. Is the angular momentum of the system constant? 2. Relevant equations This is mainly a conceptual question, but anywho: L = I * omega L initial = L final 3. The attempt at a solution What do I do with the information that the woman is standing at the western rim? I'm a bit lost with the concepts of this unit that we're doing in class so any clarification/explanations would be much appreciated !
