Question

Two projectiles are fired with same initial speed of u, one at an angle of 420 other at 49°. They attain horizontal range of R₁ and R₂ such that.​

Answer 1

Answer:

The horizontal range is the same when the angle of projection is θ or (90 0 −θ).

In other ways,

For this projectile motion,

θ 1 +θ 2 =90°
