On a Gravitron ride, people are pressed against the wall while the entire chamber spins. Suppose that the distance from the center of the chamber to a 75 kg person held flat against the wall is 2.6 m. (a) If the coefficient of static friction between the person and the wall is 0.50, what is the minimum value of the normal force on the person so that the person will be held up against their own weight?

(b) How fast must the chamber be turning to produce the minimum normal force?
