Homework Statement
The coefficient of static friction between a small coin and a turntable is 0.30. The turntable rotates at 33.3 RPM. What is the max distance from the center of the turntable at which the coin will not slide?

The Attempt at a Solution
Didn't get very far. How can this be done without the mass of the coin, or the normal force supporting it? The Force of static friction is the only horizontal force acting on the coin, correct? When the inertia of the coin overcomes this Force of static friction, the coin will slide, correct?
