In an amusement ride, fun seeking people enter a 7.4 meter diameter cylinder and stand up against the wall. The cylinder spins fast enough so that when the bottom drops down 2 meters, the people remain pinned to the wall. The cylinder continues to rotate for awhile but then slows down and the people slowly slide down the wall. Assuming that a person has a mass of 75 kg and the coefficient of static friction is 0.56 with the wall, at what rpm will that person begins to slide down?
