Two projectiles are fired from ground with same initial speeds from same point at angles (45° + α) and (45° - α) with horizontal direction. The ratio of their times of flights is

Asked in JEE Main 7th April 1st Shift 2025 · Time of flight

Answer: (4) (1 + tan α)/(1 - tan α)

Step-by-step solution

T ∝ sin θ. (T₁)/(T₂) = (sin(45° + α))/(sin(45° - α)) = (cos α + sin α)/(cos α - sin α).

Divide by cos α: (1 + tan α)/(1 - tan α).
