1. The problem statement, all variables and given/known data A coin is placed on a turntable that is rotating at 45.0 rpm. If the coefficient of static friction between the coin and the turntable is 0.186, how far from the center of the turntable can the coin be placed without having it slip off? 2. Relevant equations mv^2/r <= usmg us= coefficient of static friction 3. The attempt at a solution I tried using the equation and I converted 45 rpms to rad/sec and I got r=12.17 but this is wrong so I don't know what to do. Maybe im using the wrong equation?
