Answer to Question #1667 in Mechanics | Relativity for dayne
A simple pendulum has a period of 3.6 s. What is its length? Answer in meters.
The period and the length of mathematical pendulum are related by the following expression:
T = 2 π √(L/g)
Thus the length is L = T2g/4π2 = 3.62* 9.8 / (4*3.142) = 3.22 [m]
