A coin is placed 18.0 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 35.0 rp (revolutions per minute) is reached, at which point the coin slides off. Part A- What is the coefficient of static friction between the coin and the turntable? Express your answer using three significant figures.

A wheel is rotating about an axis that is in the z-direction. The angular velocity ωz is -6.00 rad/s at t = 0, increases linearly with time, and is +4.00 rad/s at t = 19.0 s . We have taken counterclockwise rotation to be positive. How long is the time interval during which the speed of the wheel is increasing?
