At amusement parks, there is a popular ride where the floor ofa rotating cylindrical room falls away, leaving the backs of theriders "plastered" against the wall. Suppose the radius of the roomis 3.20 m and the speed of the wall is13.0 m/s when the floor fallsaway.
How much centripetal force (in Newtons) acts on a 55.0-kg rider ? and
What is the minimum coefficient of static friction that mustexist between a rider's back and the wall, if the rider is toremain in place when the floor drops away?
