Question

Two balls, A and B, are projected simultaneously from two points on the same level horizontal ground. Ball A is projected with speed u₁ at an angle θ₁ with the horizontal, and Ball B is projected towards A with speed u₂ at an angle θ₂ with the horizontal. For the balls to collide in mid-air, which o

Accepted Answer

Answer: u₁sinθ₁ = u₂sinθ₂ — For two projectiles launched simultaneously from the same ground level to collide in mid-air, their vertical heights must match at every instant. Since gravity acts equally on both, their initial vert
