2. A fighter jet flying horizontally at two thousand mph ten thousand feet above ground, fires a projectile straight up with an initial speed of four thousand mph. Find the range r and the time of flight t to the place where the projectile hits the ground. Let r = hĝ+ dû where ĝ is the unit direction of gravity and û = ĝi is the unit horizontal pointing in the direction the plane is moving at the time when it fires the projectile. (A) t= 10 minutes, 8 = 2.5 miles. (B) = 62 minutes, 8 = 23.5 miles. (C) t= 12 minutes, & 401.5 miles. (D) t 5 minutes, & 200.5 miles.
