Problem

A particle’s velocity–time graph is a straight line passing through the points

(0\,\text{s},\,2\,\text{m\,s}^{-1})

and

(6\,\text{s},\,20\,\text{m\,s}^{-1})

. The magnitude of its acceleration is a)

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

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

\dfrac{1}{3}\,\text{m\,s}^{-2}

\dfrac{10}{3}\,\text{m\,s}^{-2}
