Question:
A woman of mass m67 kg is standing on the edge of a horizontal disk of radius R m and mass M kg The disk is at rest and is free to rotate about a frictionless vertical axis through its center. She starts walking clockwise along the edge with a constant velocity of ms with respect to the Earth the moment of inertia about the disk's center of mass is IMR
a In what direction and with what angular speed does the turntable rotate?
b How much chemical energy does the womans body convert into mechanical energy of the woman–turnable system as the woman sets herself and the turntable into motion?
