Problem: A coin is placed 14.7 cm from the axis of a rotating turntable. The coefficent of static friction between the coin and the turntable is .51. The speed of the turntable is slowly increased until the coin slides off.
Part A: What is the speed (in RPM) of the turntable when the coin falls off?
I need help to determine the speed (in RPM) of the turntable when the coin falls off.
