Question $5$ of $10$

A model rocket blasts off and experiences an accoleration described by the function a $($n$)=101-{61}^2,$ where $a($i$)$ is in moters$/$sec$?$ Find the function which describes the velocity of the rocket in it is moving upwards at $3$ meters $\frac{?}{sec}$ at $\frac{?}{?}=1$

$v(i)=8i^2-2i^3-3$

$v(0)=8P^2-2P^3$

$v(t)=16-t$

$v(t)=\frac{8}{3}{t}^3-\frac{1}{2}{t}^4-3t$
