where do i begin?

A 3.20g coin is placed 19.0cm from the center of a turntable. The coin has static and kinetic coefficients of friction with the turntable surface of (u)static=0.900 and (u)kinetic=0.400.

What is the maximum angular velocity with which the turntable can spin without the coin sliding?

Do you know the equation for centripetal force? You can see it increases with angular velocity, so at a certain point it will be greater than the force of friction, and the coin will begin to move.
