A penny of mass 3.1g rests on a small 28.2g block supported by a spinning disk of radius 12cm. The coefficients of friction between the block and disk are .73 (static) and .64 (kinetic) while those for the penny and black are .6 (static) and .45 (kinetic). What is the maximum speed of the disk without the block and penny sliding?

Answer in units of rpm
