# Question: a coin rests 132 cm from the center of a...

###### Question details

A coin rests 13.2 cm from the center of a turntable. The coefficient of static friction between the coin and turntable surface is 0.350. The turntable starts from rest at t = 0 and rotates with a constant angular acceleration of 0.661 rad/s2. (a) Once the turntable starts to rotate, what force causes the centripetal acceleration when the coin is stationary relative to the turntable? Under what condition does the coin begin to move relative to the turntable?

(b) After what period of time will the coin start to slip on the turntable? s
