Chapter A.10, Problem 115AYU

To determine

To find: Theperiod $T$ of the pendulum.

Answer to Problem 115AYU

The time period is $0.906\text{sec}$ .

Explanation of Solution

Given:

The length of the pendulum is $l=8\text{inches}$ .

Calculation:

Consider the expression for the Time period of the pendulum is,

  $T=2\pi \sqrt{\frac{l}{32}}$

Then,

  $\begin{array}{c}T=2\pi \sqrt{\frac{8\text{inches}}{32}}\\ =2\left(3.14\right)\sqrt{\frac{\text{0}\text{.666667}\text{ft}}{32}}\\ =0.906\text{sec}\end{array}$
