A simple harmonic oscillator consists of a 0.50 kg block attached to a spring. The block slides back and forth along a straight line on a frictionless surface with equilibrium point x = 0. At t = 0 the block is at x= 0 and moving in the positive x direction. A graph of the magnitude of the net force F on the block as a function of its position is shown in Figure. The vertical scale is set by Fs = 75.0 N. What are?(a) The amplitude and(b) The period of the motion,(c) The magnitude of the maximum acceleration, and(d) The maximum kinetic energy?
