JEE Main 2022 (26 Jun Shift 1)

Question

A fighter jet is flying horizontally at a certain altitude with a speed of 200 m s-1. When it passes directly overhead an anti-aircraft gun, a bullet is fired from the gun, at an angle θ with the horizontal, to hit the jet. If the bullet speed is 400 m s-1, the value of θ will be _____ °.

Correct answer
60

Step-by-step explanation

In order to hit, horizontal velocity of both moving object should be same,

V1=V2cosθ ⇒200=400cosθ

⇒cosθ=12 ⇒θ=60°
