A carnival Rotor-ride has radius R = 5.0 m and a frequency of rotation f = 0.50 rev/s. What is the minimum coefficient of static friction μs, that will keep a person of mass m from sliding down when the bottom falls out? Let Ffr = Force of friction A) μs = 0.20 B) μs = 0.51 C) μs = 0.13 D) μs = 0.29 E) μs = 0.46 F) None of these
