Homework Statement
In a "Rotor-ride" at a carnival, riders are pressed against the inside wall of a vertical cylinder 2.0m in radius rotating at a speed of 1.1 revolutions per second when the floor drops out. What minimum coefficient of friction is needed so a person won't slip down? Is this safe?
Homework Equations
The Attempt at a Solution
I set friction equal to the net force and then solved for mu, which I'm not sure is right or not:
[tex]umg = m(v^2/r)[/tex]
