P15.106 A Simple harmonic oscillator is a block attached to a spring with constant k = 200 N/m. The block slides on a frictionless surface with equilibrium point x = 0 to maximum amplitude 0.2 m. See the graph of the block's velocity below, ts = 0.2 s. What are (a) the period of the SHM, (b) the block's mass, (c) its displacement at t = 0, (d) its acceleration at t = 0.1 s, and (e) its maximum kinetic energy?
