$P=\frac{\pi}{4}$ seconds $T=\frac{4}{\pi}$ oscillations/second
Since we know that the length is 0.5 ft, we can use the following formula to find the period P: $P=2\pi\sqrt {\frac{L}{32}}$ $P=2\pi\sqrt {\frac{0.5}{32}}$ $P=2\pi\sqrt {\frac{1}{64}}$ $P=2\pi(\frac{1}{8})$ $P=\frac{\pi}{4}$ seconds The frequency T is a reciprocal of period P. Therefore, $T=\frac{1}{P}=\frac{1}{\frac{\pi}{4}}=\frac{4}{\pi}$ oscillations/second
