1 0.5 (m) x 0.5 -0.5 -1 4 1.5 D 2.5 B t (s) The graph above shows the position of an object in simple harmonic motion as a function of time. What are the first two times after zero at which the object has its maximum acceleration? t = S What is the absolute value of the maximum acceleration? S Hints: $|F| = ma$ and by Hooke's law $|F| = k\Delta x$. The period of a mass-spring system in SHM is $T = 2\pi/\sqrt{(m/k)}$. Solve for $k/m$, then find $a$. amax = 2 m/s²
