Questions
A fighter plane flying horizontally passes over an antiaircraft gun with a uniform velocity 200 ms-1. The gun can fire the shell with a velocity . At what angle should the gun fire the shell so as to hit the plane?
detailed solution
Correct option is A
Let velocity of shell = U and velocity of plane = V and θ be the angle at which shall is fired to hit the plane, thenUcosθ=V⇒cosθ=VU=2002002cosθ=12⇒θ=45∘Talk to our academic expert!
