Mints on a Rotating Turntable - Determining the Static Coefficient of Friction (6:47)

A turntable is turning 45 revolutions per minute. Mints are located 0.030 m, 0.080 m, and 0.130 m from the center of the record. Determine what you can about the coefficient of static friction between the turntable and the mints. This is an AP Physics 1 topic.
