An airplane is flying at a constant height of 3000 ft abovewater at a speed of 400 ft/s
Chapter 0, Problem 55(choose chapter or problem)
An airplane is flying at a constant height of \(3000ft\)above water at a speed of \(400ft/s\). The pilot is to release a survival package so that it lands in the water at a sighted point \(P\). If air resistance is neglected, then the package will follow a parabolic trajectory whose equation relative to the coordinate system in the accompanying figure is
\(y=3000-\frac{g}{2 v^{2}} x^{2}\)
where \(g\) is the acceleration due to gravity and \(v\) is the speed of the airplane. Using \(g=32 \mathrm{ft} / \mathrm{s}^{2}\), find the "line of sight" angle \(\theta\), to the nearest degree, that will result in the package hitting the target point.
