A penny of mass 310 gram rests on a small 200 gram block


A penny of mass 3.10 gram rests on a small 20.0 gram block supported by a spinning disk. The coefficients of friction between block and disk are 0.750 (static) and 0.640 (kinetic) while those for the penny and block are 0.520 (static) and 0.450 (kinetic). Find the maximum rate of rotation in revolutions per minute that the disk can have, without the block or penny sliding on the disk?
