A coin of mass m=10.00 g is placed at R=16.00 cm from the center of a rotating, horizontal turntable. The coin has static and kinetic coefficients of friction with the turntable surface of u,=0.90 and H = 0.72, respectively. (a) If the turntable is sping at an angular velocity of 5.20 rad/s, how much is the friction between the coin and the turntable? Answer: (b) What is the maximum angular velocity at which the turntable can spin without the coin sliding? Answer: rad/s.
