If a freely falling body starts from rest, then its displacement is given by $s=\frac{1}{2}gt^2.$ Let the velocity after a time $T$ be $V$.

(a) What is the average velocity $v_{ave}$ if we compute the average of the velocities with respect to $t$?

$v_{ave} =$

(b) What is the average velocity $v_{ave}$ if we compute the average of the velocities with respect to $s$?

$v_{ave} =$
