Problem

An automobile travels straight down a highway at

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

. If each tire has an effective radius of

0.32\,\text{m}

, what is the angular speed of a tire in radians per second? a)

4.2\times 10^{1}\,\text{rad}\!/\!\text{s}

2.7\times 10^{2}\,\text{rad}\!/\!\text{s}

8.4\times 10^{1}\,\text{rad}\!/\!\text{s}

1.3\times 10^{1}\,\text{rad}\!/\!\text{s}
