Two projectiles are fired at equal speeds but differentangles. one is fired at an angle of 30 degrees and the other at 60degrees. the projectile to hit the ground first wil be the onefired at (neglect air resistance)a-30degreesb-60 degreesc- both hit at the same time

a) 30 degree

Explanation:

As we know that time of flight of the projectile depends on the the vertical component of the velocity always

It is given as

now we know that

so we will have

since we know that two projectiles are projected at same speed but different angles

so smaller the angle will take smaller time

so it would be 30 degree projectile which will take smaller time
