The other end of the spring is fixed, so that the spring is horizontal. cylinder is able to roll on the table without slipping. Let's pull the mass to one side and release it so that it rolls back and forth. The Show that the motion of the center of mass is simple harmonic, and find the frequency of ocillation, w. HINT: There are two ways (at least) to do this. Each involves comparing information about this system to the simple harmonic ocillator we know, the mass on a spring.
