Cooper Section $8\mathrm{.}4\backslash$#$4$

Acceleration is the rate of change of velocity. The velocity $($positive means down$)$ of a pumpkin thrown off the top of Cheadle hall $\backslash ($ t $\backslash )$ seconds after launch is $\backslash (32$ t $\backslash$mathrm$\{$ft$\}/\backslash$mathrm$\{$sec$\}\backslash )($until it hits the ground$).$

a$.$ What is the average rate of change of velocity between $\backslash ($ t$=1\backslash )$ and $\backslash ($ t$=2\backslash )?$ feet per second per second

b$.$ What is the average rate of change of velocity between $\backslash ($ t$=1\backslash )$ and $\backslash ($ t$=1\mathrm{.}1\backslash )?$ feet per second per second

c$.$ If the pumpkin lands after $3$ seconds, what is the speed of the pumpkin when it hits? feet per second
