Question
![8. A student performs a simple experiment to find the average acceleration of a
falling object. He drops a baseball from a building and uses a string and meter
stick to measure the height the ball was dropped. He uses a stopwatch to find an
average time of fall for 3 trials from the same height and reports the following
data: h = 5.25 ± 0.15 m, t = 1.14 ± 0.06 s. Use the equation a = 2h/(t^2) to
determine the average acceleration and its uncertainty. *
A. 8.08 + 0.1 m/s^2
B. 8.08 ± 0.88 m/s^2
