Problem

A car is at position

x=15\,\text{m}

t=0\,\text{s}

and at position

x=90\,\text{m}

t=5.0\,\text{s}

. Its velocity at

t=0\,\text{s}

6.0\,\text{m}\!/\!\text{s}

and the acceleration is constant. Determine the car’s average acceleration during this

5.0\,\text{s}

interval. Include the correct units in your answer.
