Answer
36 ft
Work Step by Step
Free fall model:
\[
\begin{array}{l}
v(t)=-g t+v_{0} \\
s(t)=v_{0} t-\frac{1}{2} g t^{2}+s_{0}
\end{array}
\]
\[
48=-32 t+0
\]
Thus $t=\frac{3}{2}$
$g=32$, $v_{0}=0$ and $v(t)=48$ in the velocity formula
\[
0=-\frac{1}{2} \cdot 1.5^{2} \cdot 32+s_{0}
\]
In the position formula
$s_{0}=36$
$s(t)=0, t=1.5, v_{0}=0$, $v(t)=48$ and $g=32$
