Activity 1.1.4

For the function given by $s(t) = 64 - 16(t-1)^2$ from Preview Activity, find the most simplified expression you can for the average velocity of the ball on the interval $[2, 2+h]$. Use your result to compute the average velocity on $[1.5,2]$ and to estimate the instantaneous velocity at $t = 2$. Finally, compare your earlier work in Activity.
