MDCAT Physics QUESTION #4403
Question 1
A ball is thrown into the air with velocity $v$ making angle $\theta$ with horizontal. If air resistance is neglected, at maximum height its velocity is:
  • Equal to initial velocity
  • Half of initial velocity
  • Equal to zero
  • Minimum but not zero✔️
Correct Answer Explanation
At maximum height, the vertical component of velocity $v_y = 0$. However, the horizontal component $v_x = v\cos\theta$ remains unchanged (no air resistance). So velocity is minimum but not zero (unless $\theta = 90°$).
