Question

Tarzan swings back and forth on a

vine with a period of 7.27 s. How
long is the vine?
(Unit = m)

Answer 1

Answer: 13.1

Step-by-step explanation:

Answer 2

Considering Tarzan as a point mass at point L and using the equation for a simple pendulum:

P = 2 pi (L / g)1/2

P^2 = 4 pi^2 L / g

L = g P^2 / (4 pi^2) = 9.8 m/s^2 * 7.27^2 s^2 / (4 pi^2) = 13.1 m
