Questions
Which one of the following gives the angle made by the resultant velocity after t seconds for projectile of initial velocity u, projected at an angle with the horizontal ?
detailed solution
Correct option is C
Here vx=ucosθ and vy=usinθ−gt∴ tanα=VyVx=usinθ−gtucosθ=tanθ−gtucosθ∴ α=tan−1tanθ−gtucosθTalk to our academic expert!
