Question 1

The speed of a projectile at its maximum height is half its initial speed. The angle of projection is:

  • $15°$
  • $30°$
  • $45°$
  • $60°$✔️
Correct Answer Explanation

At max height, speed $=$ horizontal component $= u\cos\theta$.

Given: $u\cos\theta = \dfrac{u}{2} \Rightarrow \cos\theta = \dfrac{1}{2} \Rightarrow \theta = \mathbf{60°}$
