Problem

The position–time graph of a pendulum undergoing small-amplitude simple harmonic motion reaches a maximum displacement of

+0.12\,\text{m}

t = 0.10\,\text{s}

and a maximum displacement of

-0.12\,\text{m}

t = 0.35\,\text{s}

. What is the best estimate of the frequency of the oscillation? a)

4.0\,\text{Hz}

8.0\,\text{Hz}

2.0\,\text{Hz}

0.50\,\text{Hz}
