Homework Statement
In a "rotor-ride" at a carnival, people rotate in a vertical cylindrically walled room. If the room radius was 5.5m, and the rotation frequency 0.50 revolutions per second when the floor drops out, what minimum coefficient of static friction keeps the people from slipping down?
Homework Equations
F(friction)</= usF(normal)
F(normal)=mg
us=g/(T*r)
The Attempt at a Solution
us=g/(T*r)
us=9.8/(2*5.5)
us=.891
