A ball is thrown straight down from the top of a $405-$foot building with an initial velocity of $-23$ feet per second. Use the position function below for free$-$falling objects.

$s(t)=-16t^2{v}_{0}t{s}_0$

What is its velocity $($in $f\frac{t}{s})$ after $3$ seconds?

$v(3)=f\frac{t}{s}$

What is its velocity $($in ft$/$s$)$ after falling $348$ feet?

$v=$ ft$/$s
