In a Rotor-Ride at a carnival, riders are pressed against the inside wall of a vertical cylinder 2.00 m in radius rotating 1.10 revolutions per second when the floor drops out.
(a) What is the speed of a rider in m/s?
(b) What is the acceleration of a rider?
(c) What minimum coefficient of static friction is needed so that the rider will not slip down the inside wall of the cylinder?
