Questions
Two particles are projected in air with speed u at angles (both acute) to the horizontal, respectively. If the height reached by the first particle is greater than that of the second, then which one of the following is correct?
detailed solution
Correct option is A
Height H = u2sin2θ2gFor the same speedH ∝ sin2 θ∵ H1 > H2 (Given)∴ sin2θ1 > sin2θ2or θ1 > θ2----------(i)Time of flight, T = 2u sinθgFor the same speedT ∝sin θθ1 > θ2 (From (i))∴ sin θ1 > sin θ2 ⇒ T1 > T2Talk to our academic expert!
