Problem
An object oscillates in simple harmonic motion along a straight line. The acceleration–time graph for the motion is described below.
• The acceleration varies sinusoidally with period 0.80s.
• The minimum value on the graph is −2.0ms−2 at t=0.
• The graph crosses zero acceleration for the first time at t=0.20s.
Use this information to determine key dynamic quantities of the motion.
(a) Determine the frequency f of the oscillation.
(b) Calculate the amplitude A of the displacement.
(c) Compute the object’s maximum speed vmax.
