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. a) Use the equation a = 2h/t? to determine the average acceleration and its uncertainty. b) Comment on the accuracy of the acceleration result. Do you think the student made any mistakes? c) What one suggestion would you tell this student to improve the experimental result? Please explain.
