Two projectiles are fired from ground level at equal speeds but different angles. One is fired at an angle of 30° and the other at 60°. Neglecting air resistance, the projectile to hit the ground first will be the one fired at
A)30°.
B)60°.
C)both hit at the same time

Question

Quizplus · Accepted Answer

The time taken for a projectile to hit the ground is determined by the vertical component of its velocity. The vertical component of velocity is given by Vsinθ, where V is the initial velocity and θ is the angle of projection. Since the projectiles are fired at equal speeds, the projectile with a smaller angle of projection (θ=30°) will have a larger vertical component of velocity compared to the one fired at a larger angle (θ=60°). Therefore, the projectile fired at 30° will hit the ground before the other projectile.
