## Homework Statement

At an amusement park, some physics students are on a ride where they stand against the wall in a cylindrical apparatus that begins to rotate around its center. Once they are moving fast enough the floor drops and they “stick” to the wall due to friction. The radius of the cylinder is R = 3.5 m and the minimum speed the ride must move the people at to keep them from sliding down the wall is 10 m/s. What is the coefficient of static friction between the student and wall?

## Homework Equations

Friction = mu * normal

a = V^2 / r

## The Attempt at a Solution

I am not sure how to start and which equation I need to use. The answer is supposedly 0.34, but I don't know how to get there.
