Problem

A data logger records the speed of a stone that is dropped from rest. The speed is

9.7\,\text{m/s}

after

1.0\,\text{s}

and

29.1\,\text{m/s}

after

3.0\,\text{s}

. Using these two readings, determine the numerical value of

g

. (a)

14.6\,\text{m/s}^{2}

(b)

6.5\,\text{m/s}^{2}

(c)

9.7\,\text{m/s}^{2}

(d)

19.4\,\text{m/s}^{2}
