Problem

A body starts from rest, accelerates uniformly for

6\,\text{s}

until it reaches a speed of

12\,\text{m\,s}^{-1}

, and then continues to move at this constant speed for another

4\,\text{s}

. Describe qualitatively the shape of its velocity–time graph for the entire

10\,\text{s}

interval.
