Question

A simple pendulum is swinging back and forth through a small angle, its motion repeating every 1.08 s. How much longer should the pendulum be made in order to increase its period by 0.31 s?
The Formula for this Problem is T= 2ð*radical (L/g). After solving for L, the new for Formula becomes: g(T^2/4ð^2) = L ... Now you Plug in your Numbers. remember you looking for the difference. It should be Something like this: (9.8*(1.08+0.31)^2)/(4ð^2)-(9.8*(1.08)^2)/(4ð^2). the Answer should be 0.190 meter.
