2019-7-6 · 30 ft is a very long pendulum. The period T of a pendulum (the time it takes for one swing back to where it started) is approximately T≈2π√(Lg) where L is the length and g=32 fts 2 is the acceleration due to gravity. In your case, L=30 ft, T≈6 s. Now, if you watch a kid swing a much shorter swing, you will see that they "pump" once per
