A fighter plane flying horizontally at an altitude of 1.5 km with speed 720 kmh^(-1) passes directly over head an anticraft gun. At what angle from the vertical should the gun be fired from the shell with muzzle speed 600 ms^(-1) to hit plane. At what minimum altitude should the pilot fly the plane to avoid being hit ? ( Take g= 10 ms^(-2) ).

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