Here are some questions you’ll be asked after you finish watching the videos. Please read through these before watching the videos.

An object is moving forward along a straight line. The distance the object travels (in meters) from its starting position $t$ seconds after it started moving is given by $s(t) = 2 \sqrt {t}$ . Determine the average velocity of the object over the interval from $t = 4$ to $t = 9$ .

Compare the average rates of change of the functions $f$ , $g$ , and $h$ over the interval $[2, 10]$ .
