An Aeroplane flies horizontaily at a height h at a speed v. An anti-air craft gun fires a shell at the plane when it is vertically above the gun. Show that the minimum muzzle velocity required to hit the plane is `sqrt(v^2+2gh)` at an angle `tan^(-1)((sqrt(2gh))/(v))`

An aeroplane flies horizontally at a height h at speed v. An anti - carft gun a shell at the plane when it is vertically above the gun . Show that the minimum muzzle velocity required to hit the plane is sqrt(v^(2) + 2gh) at an angle tan^(-1) ((sqrt(2gh))/(v)) .

A jet plane files horizonally at a height h at a speed v. An anti-aircraft gun fires a shell at the plane when it is vertically above the gun. Show that the minimum muzzle speed required to hit the plane is sqrt(v^(2)+2gh) at an angle tan^(-1)sqrt(2gh)/(v)

A figher plane flying horizontal at an altitude of 1.5 km with a speed of 720 km/h passed directly overhead an anti-aircraft gun. At what angle from the vertical shoud the gum be fired for the shell with muzzle velocity of 600 m/s to hit the plane ? At what minimum altitude should the pilot fly to avoid being hit ? g= 9.8 m/ s^2

A fighter plane flying horizontally at an altitude of 1.5 km with speed 720 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"ms"^(-1) to hit the plane ? At what minimum altitude should the pilot fly the plane to avoid being hit ? (Take g= 10 " ms "^(-2)) .
