A 550 g mass is attached to a horizontal spring (k = 155 N/m) on a frictionless surface. It is at rest at the equilibrium position. At t 0 s, is struck by a hammer, which gives it an initial speed of 2.15 m/s. Determine (a) the frequency of motion, (b) the amplitude, (c) the maximum acceleration, and (d) the total energy.
