A 50kg woman is in a rotor with a 2m radius, laying against theinner surface. The friction between the woman’s sweater andthe surface is μs = 0.5. (a) The rotor begins spinning with aconstant angular acceleration α, and when the rotor reachesenough angular speed, the floor drops but the woman stays stickingto the wall. (a) What is the minimum angular velocity that willallow the woman not to fall down when the floor drops? (b)What’s the maximum angular acceleration that will not makethe woman slide along the wall when the rotor is speeding up to the angular velocity calculated in (a)?
