Determine the length of a mathematical pendulum with an oscillation period of 3.14 s. The pendulum is on the Moon, the acceleration of gravity on the Moon is g (l) = 1.62 m / s ^ 2.
We have the formula for the periodicity of the pendulum oscillation: T = 2п√l / g
from it we find the length l = gT² / 4п² = 1.62 / 4 = 0.405 m.
Answer: the length of the pendulum is 0.405 m
