Problem

An object moves so that its velocity–time graph is a horizontal line at

6\,\text{m/s}

from

t=0

4\,\text{s}

and then a straight line decreasing uniformly to

0\,\text{m/s}

t=7\,\text{s}

. How much distance does the object travel in the entire

7\,\text{s}

interval? a)

36\,\text{m}

33\,\text{m}

24\,\text{m}

42\,\text{m}
