A 9.60 g coin is placed 10.7 cm from the center of a turntable. The coin has a coefficient of static friction of 0.80 and a coefficient of kinetic friction of 0.60 with the turntable. The turntable's angular velocity slowly speeds up until the coin starts to slide off. Assuming that the local acceleration due to gravity is -9.80 m/s2?, calculate the angular speed (in rev/min) where the coin slides off.
