A homogeneous disc of weight \( W \) and radius \( R \) rotates about the vertical axis \( O Z \), the initial angular velocity being \( \omega_{0} \). During the motion, the brake block \( A \) is pressed to the disc, with a radial force \( N \) for \( t_{0} \) seconds and the disc comes to rest because of friction. Find the coefficient of friction.
