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. Suppose the radius of the room is 1.2 m. If the coefficient of static friction between a rider's back and the wall is 0.214, what is the minimum rotation speed of the cylindrical room in of revolutions per minute (rpm) if the rider is to remain in place when the floor drops away? Use g=10 m/s².
