A fighter plane is flying horizontally at an altitude of $1.5km$ with speed $720km/h$. At what angle of sight (with respect to horizontal) when the target is seen, should the pilot drop the bomb in order to attack the target.

Q. A fighter plane is flying horizontally at an altitude of 1.5 km with speed 720 km/h. At what angle of sight (w.r.t. horizontal) when the target is seen, should the pilot drop the bomb in order to attack the target than?

Q. A fighter plane flying horizontally at an attitude of 1.5 km with a speed of 720 km/h passes directly overhead of an antiaircraft gun. At what angle from the horizontal should the gun be fired for the shell muzzle speed 600 m/s to hit the plane? At what minimum altitude should the pilot fly the plane to avoid being hit. [ g = 10 $m/s^2$]

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

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

Q. A fighter plane flying horizontal at an altitude of 1.5 Km with speed of 720 Km $h^{-1}$ passes directly overhead an anticarft gun. At what angle from the vertical should the gun be fired from the shell with muzzle speed 400 $m{s}^{-1}$ to hit the plane in shortest time.?
