Consider the potential energy described in problem 1.14. For low
amplitudes, the motion of the object is well described by simple
harmonic motion, so that the period is independent of amplitude.
However, once the amplitude gets high enough this is no longer
true. As the amplitude increase, does the period increase or
decrease? Explain your reasoning thoroughly, and assume that the
amplitude is always less than pi/B.
