Chapter 6, Problem 16P

A simple pendulum of length $L=100$ cm is shown in Fig. P6.16. The angular displacement $\theta \left(t\right)$ in radian is given by

(a) Find the amplitude, frequency, and period of oscillation of $\theta \left(t\right)$.

(h) Find the time required for the simple pendulum to reach its first zero angular displacement (i.e., $\theta \left(t\right)=0$ ).

(e) Plot one complete cycle of $\theta \left(t\right)$, and indicate the amplitude and period on the graph.
