Homework Statement
In a carnival ride, passengers stand with their backs against the wall of a cylinder. The cylinder is set into rotation and the floor is lowered away from the passengers, but they remain stuck against the wall of the cylinder. For a cylinder with 2m radius, what is the minimum speed of that passengers can have fr this to happen if the coefficient of friction between the passengers and the wall is 0.25.
Homework Equations
[tex]\mu[/tex]= Friction/normal force
Centripetal force= (mv^2)/r
The Attempt at a Solution
I don't understand how I would go about the equation if I'm not given the mass of the passenger. Because I can't find the friction force through the normal force (because I don't have mass). Is there another way to approach it?
Thanks!
