Homework Statement
A coin is off-center on a turntable which is spinning at a constant velocity. The coin is not slipping. From what I have gathered, the radial acceleration of the coin is caused by the force of static friction on the coin. There is no tangential acceleration.
Homework Equations
The Attempt at a Solution
Exactly why is there a static friction force there? I've been trying to figure this out, but nothing makes sense. Needing to take in the rotation is goofing me up since I don't have much groundwork in rotating things (enough to come up with this problem, understand the problem, and word it, but not enough to solve it).
The coin has a tangent velocity. Shouldn't the friction force be tangent as well, but pointing in the other direction?
