A Relief Package Is Dropped from an Airplane and Falls $h$

Short Answer

A relief package is dropped from an airplane and falls to the ground along a parabolic path, starting at the vertex of the parabola. The package was released when the plane was directly above a marker at a height of 5 kilometers, and the package hits the ground 4.63 kilometers from the marker. If $h$ is the height of the package when it is a horizontal distance $d$ from the marker, the equation for $h$ in terms of $d$ is given by $h(d)=a d^{2}+b d+c$ , where $a=\ldots, b=\ldots$ , and $c=\ldots$ .
