At amusement parks, there is a popular ride where the floor of a rotating cylindrical room falls away, leaving the backs of the riders "plastered" against the wall. Assume the radius of the room is 3.25 m and the speed of the wall is 12.8 m/s when the floor falls away.
a) What is the source of the centripetal force acting on the riders?
The strong force among the rider and the wall the normal force exerted on the rider by the wall the gravitational force the cavitron force between the wall and the rider.
b) How much centripetal force acts on a 55.0 kg rider?
c) What is the minimum coefficient of static friction that should exist between the rider's back and the wall, if the rider is to remain in place when the floor drops away?
