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 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 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 gun fires a bullet with a speed of 400m//s . What is recoil velocity of the gun if its mass is 200 times the mass of the bullet?

An aircraft moving with a speed of 1000 km/h is at a heirgh of 6000 m, just overhead of an anti-aircraft gun. If the muzzle velocity of the gun is 540 m/s, the firing angle theta for the bullet to hit the aircraft should be

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

A gun fires a bullet at a speed of 140 ms^(-1) .If the bullet is to hit a-target at the same level as the gun and at 1km distance, the angle of projection may be

From an automatic gun a man fires 360 bullet per minute with a speed of 360 km/hour. If each weighs 20 g, the power of the gun is
