9) The Rotor" is a fun carnival ride. It's made of a large hollow cylinder of radius R, that's rotated rapidly about the center axis. A rider stands with her back against the inner wall. At a certain speed, the floor drops, but the rider does not fall. a. Draw a diagram of this scenario (Hint: use a view from the side). Label all forces. Which force prevents the rider from falling? Which force supplies the centripetal force? If the coefficient of static friction between the rider and the wall is what is the minimum speed the cylinder must rotate to keep the rider in place? You answer should be an expression, in variables. Describe what the rider feels during the ride. Does this match what an outside observer would describe? Why or why not? c.
