Question

Two projectiles are projected with the same velocity. If one is projected at an angle of 30^o and the other at 60^o to the horizontal. The ratio of maximum heights reached, is

Answer · 5 votes

When a projectile is projected with a velocity, u and at angle, theta to the horizontal, the maximum height reached by the projectile is given by, H = u^2sin^2theta2g As both projectiles have same projected velocity, so H ∝sin^2theta Thus ratio of maximum heights H30H60 = sin^230sin^260 = 1/43/4 = 1/3
