Learning Goal: apply principles of static friction and circular motion to analyze the motion of a person on a spinning carnival ride. In a classic carnival ride, patrons stand against the wall in a cylindrically shaped room. Once the room gets spinning fast enough, the floor drops from the bottom of the room! Friction between the walls of the room and the people on the ride makes them "stick" to the wall so they do not slide down. 6.8 m In one ride, the radius of the cylindrical room is R and the room spins with a frequency of 22.1 revolutions per minute. R A bo What is the magnitude N of the normal force of the wall on = 45.0 kg? a rider of mass m = @Macmillan Learning N = N
