The stacked blocks in the diagram are moving in simple harmonic motion on the end of the spring. The horizontal surface is frictionless, but m is held in place on M only by static friction.

The blocks’ motion is described by the position equation x = (15 cm)Cos(2pt + ½ p).

Calculate the minimum coefficient of static friction between the two blocks so that m remains in place on M throughout the simple harmonic motion.
