What is maximum speed of disk without block-penny sliding

Reference no: EM13563374

A penny of mass 3.1 g rests on a small 13 g block supported bya spinning disk of radius 11 cm. The coefficients of frictionbetween block and disk are 0.755 (static) and 0.64 (kinetic) whilethose for the penny and block are 0.577 (static) and0.45(kinetic).

What is the maximum speed of the disk without the block and penny sliding? The accelertion of gravity is 9.8m/s2 (meters persecond squared). Answer in units of rpm.
