Problem

A coin is dropped from rest through a vertical height of

1.50\,\text{m}

. The measured times of fall in three independent trials are

0.553\,\text{s}

0.560\,\text{s}

and

0.557\,\text{s}

. Answer the following: a. (a) Find the average time of fall. b. (b) Using this average time, determine the experimental value of

g

. c. (c) Calculate the percentage error of this value when compared with

9.8\,\text{m\,s}^{-2}

. (Use the value obtained in part (b).)
