Chapter 13, Problem 16PCE

A mass oscillates on a spring with a period T and an amplitude 0.48 cm The mass is at the equilibrium position x = 0 at t = 0, and is moving in the positive direction. Where is the mass at the times (a) t = T/8, (b) t = T/4, (c) t = T/2, and (d) t = 3T/4? (e) Plot your results for parts (a) through (d) with the vertical axis representing position and the horizontal axis representing time.
