Explanation:
The horizontal distance traveled by the projectile is given by the formula
The formula for the time of flight is given by
Case I: when the launch angle is 30°
So,
Horizontal velocity = u Cos 30 = 0.866 u
Case II: when the launch angle is 60°
Horizontal velocity = u Cos 60 = 0.5 u
By observing the case I and case II, we conclude that
R1 = R2
Horizontal velocity 1 > Horizontal velocity 2
T1 < T2
