Problem

A car is traveling in a straight line at an initial speed of

6.0\,\text{m/s}

. The driver then accelerates uniformly at

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

for

3.0\,\text{s}

. What is the car’s speed at the end of the

3.0\,\text{s}

interval? a)

9.0\,\text{m/s}

18\,\text{m/s}

12\,\text{m/s}

6.0\,\text{m/s}
