Question

If angles of projection for two projectiles are 30° and 60° then the ratio of velocities at maximum height is:

• A. 1:1
• B. 2:1
• C. 1:2
• D. 3:1

Hint:

For projectiles, the horizontal component of velocity does not change during the flight, and at maximum height, it remains constant.

Answer 1

The Correct Option is A

At maximum height, the vertical component of velocity becomes zero for both projectiles, and only the horizontal component of velocity remains. The horizontal component of velocity is independent of the angle of projection (it is \(v \cos(\theta)\)). Hence, the velocities at maximum height for both projectiles are the same. Thus, the correct answer is 1:1.
