In a classical carnival ride, patrons stand against the wall in a cylindrically shaped room. once the room gets spinning fast enough, the floor drop from the bottom of the room! friction between the walls of the room and the people on the ride make them the "stick" to the wall so they do not slide down. in one ride, the radius of the cylindrical room is r=6.4m and the room spin with a frequency of 22.1 revolutions perminute. what is the speed of a person "stuck" to the wall and what is the normal force of the wall on a rider of m=54kg, what is the minimum coefficient of friction needed between the wall and the person.?
