Acoin is placed 10.8 cm from the axis of a rotating turntable of variable speed. when the speed of the turntable is slowly increased, the coin remains fixed on the turntable until a rate of 51.1 rpm is reached, at which point the coin slides off. what is the coefficient of static friction μs between the coin and the turntable?
