### Question Description:

A 0.33-{rm kg} mass at the end of a spring oscillates 3.0 times per second with an amplitude of 0.19 {rm m}. Determine the magnitude of the velocity when it passes the equilibrium point. Determine the magnitude of the velocity when it is 0.12 m from equilibrium. Determine the total energy of the system. Determine the equation describing the motion of the mass, assuming that at t = 0, x was a maximum and that t in seconds.
