Question
At the highest point of its trajectory, a projectile launched at an angle has a velocity that is
Correct Answer
Option C is the correct answer.
Detailed Explanation
At the apex of its trajectory, the vertical component of velocity (v_y) becomes zero for an instant. The horizontal component (v_x) remains constant throughout the motion (ignoring air resistance). Therefore, at the highest point, the projectile's velocity is entirely in the horizontal direction.
Hint
What happens to the vertical component of velocity at the top? What happens to the horizontal component?
