A fighter plane is flying horizontally at an altitude of 1.5 km with speed `720 kmh^(-1)`. 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? `(Take g=10ms^(-2))`

A helicopter is flying horizontally at an altitude of 2km with a speed of 100 ms^(-1) . A packet is dropped from it. The horizontal distance between the point where the packet is dropped and the point where it hits the ground is (g = 10 ms^(-2))

A fighter plane flying horizontally at an altitude of 1.5 km with speed of 720 km h^9-10 passes directlu overhead an anticraft gun. At what anle fro the gun with muzzle speed 400 ms^(-1) to hit the plane in shortest time ?

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) ).
