The Project: You are asked to use an iterative method to solve the following problem: You are manning an anti-aircraft gun with a muzzle velocity, Vm. An enemy aircraft is approaching on a horizontal path at a range R, an altitude H, and a speed of Vt. What should be the elevation, 0 (angle above the horizontal) of your gun to hit the target? The problem is illustrated in the figure below. Since the projectile is accelerating downward under the influence of gravity, it follows a parabolic path. The aircraft is assumed to be following a straight-line, horizontal path at constant speed. The trajectories of the projectile and the target will intersect at some point (x,y), provided that the launch angle is high enough. For a successful intercept, the projectile and target must reach the intercept point simultaneously
