Problem

A car travels

50\,\text{m}

east in

5.0\,\text{s}

and then

50\,\text{m}

west in the next

5.0\,\text{s}

. Which statement correctly describes its average speed and average velocity for the entire

10\,\text{s}

trip? a) Both the average velocity and the average speed are

0\,\text{m/s}

. b) Both the average velocity and the average speed are

10\,\text{m/s}

east. c) The average velocity is

0\,\text{m/s}

, and the average speed is

10\,\text{m/s}

. d) The average velocity is

5\,\text{m/s}

east, and the average speed is

10\,\text{m/s}
