A coin rests on a record 0.15 m from its center. The record turns on a turntable that rotates at variable speed. The coefficient of static friction between the coin and the record is 0.30.

What is the maximum coin speed at which it does not slip?

1. static =velocity squared over (radius times gravity). solve for velocity and you get velocity to equal square root (radius*gravity*static)=square root of .15*.30*9.8= .664 m/s
