A fighter jet is flying, horizontally at a certain altitude with a speed of 200 `ms^(-1)`. When it passes directly overhead an anti-aircraft gun, a bullet is fired from the gun, at an angle `theta` with the horizontal, to hit the jet. If the bullet speed is 400 m/s, the value of `theta` will be _______.

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 2km with speed of 540 kmph passes directly over head an anti aircraft gun.If the gun can fire a bullet at the muzzle speed of 500ms^( - 1) ,at what angle with the vertical the gun should fire the bullet so that the bullet hits the plane?

A fightre plane flying horizontally at an altitude oa 1.5 km with speed 720 h^(-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 showld the pilot fly the plane to avoid being hit ? ( Take g= 10 ms^(-2)).

An enemy plane is flying horizontally at an altitude of 2km with a speed of 300 ms^(-1) .An army man with an anti-aircraft gun on the ground sights enemy plane when it is directly overhead and fires a shell with a muzzle speed of 600ms^(-1) .At what angle with the vertical should the gun be fired so as to hit the plane?

An enemy air plane is flying horizontally at an altitude of 2.7km with a speed of 250ms^(-1) .An army man on the ground observed it when it is directly over his head.He fired an anti-aircraft gun with a muzzle speed of 500ms^(-1) ,such that the shell hits the plane.At what angle with the horizontal,gun should be fired?

A 50 g bullet is fired from a 10 kg gun with a speed of 500 ms^(-1) . What is the speed of the recoil of the gun.

An aircraft moving with a speed of 250 m//s is at a height of 6000 m, just overhead of an anti aircraft–gun. If the muzzle velocity is 500 m//s the firing angle theta should be:

A bullet is fired with speed 50m//s at 45^(@) angle with horizontal. Find the height of the bullet when its direction of motion makes angle 30^(@) with the horizontal.
