A coin is placed 34 cm from the center of a horizontal turntable, initially at rest. The turntable then begins to rotate. When the speed of the coin is 130 cm/s (rotating at a constant rate), the coin just begins to slip. The acceleration of gravity is 980 cm/s2 . What is the coefficient of static friction between the coin and the turntable?
