Two projectiles are fired 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 will hit at the same time.

Question

Quizplus · Accepted Answer

The time of flight for a projectile launched at an angle θ with initial velocity v is given by $T = \frac{2v\sin\theta}{g}$, where g is the acceleration due to gravity. Since $\sin(30°) < \sin(60°)$, the projectile fired at 30° will have a shorter time of flight and thus hit the ground first.
