Problem

A particle moves with the following velocity (in meters per second): •

2

for

0\le t<2

•

-1

for

2\le t<5

•

3

for

5\le t\le6

What is the particle’s average velocity over the entire time interval

0\le t\le6

seconds? a)

\displaystyle \frac{4}{3}\text{ m/s}

\displaystyle \frac{2}{3}\text{ m/s}

\displaystyle 0\text{ m/s}

\displaystyle \frac{5}{3}\text{ m/s}
