A fighter plane flying horizontally at an altitude of .1.5 km with speed 720 km/h passes directly overhead an anti-aircraft gun. At what angle from the vertical should the gun be fired for the shell with muzzle speed `600 m s^-1` to hit the plane? At what minimum altitude should the pilot fly the plane to avoid being hit? `(Take g = 10 m s^-2)`.
