Considering the given equation for the time, it is found that the length of the pendulum in this problem is of 38.40 ft.

<h3>What is the equation for the time it takes for the pendulum to swing back and forth?</h3>

The equation is given as follows:

f(l) = 2\pi\frac{l}{32}

In which l is the length of the pendulum.

In this problem, we have that f(l) = 2.4\pi, hence:

f(l) = 2\pi\frac{l}{32}

2.4\pi = 2\pi\frac{l}{32}

l = 32 x 1.2

l = 38.4 ft.
