2018 F = ma Exam A — Question 12

A group of students wish to measure the acceleration of gravity with a simple pendulum. They take one length measurement of the pendulum to be L = 1.00±0.05 m. They then measure the period of a single swing to be T = 2.00±0.10 s. Assume that all uncertainties are Gaussian. The computed acceleration of gravity from this experiment illustrating the range of possible values should be recorded as
