The period T of a simple pendulum is given by where L is the length of the pendulum and g is the acceleration due to gravity. Thus if L and T are measured, we can estimate g with
. Assume that the period is known to be T=1.5 s with negligible uncertainty, and that L is measured to be 0.559 ± 0.005 m. Estimate g, and find the uncertainty in the estimate.
