Question
In the absence of air resistance, the horizontal component of velocity for a projectile is
Correct Answer
Option A is the correct answer.
Detailed Explanation
In ideal projectile motion, the only acceleration is due to gravity, which acts vertically downward. Therefore, there is no acceleration in the horizontal direction. With zero horizontal acceleration, the horizontal component of velocity (v_x) remains constant throughout the flight.
Hint
What force (and therefore what acceleration) acts on a projectile in the horizontal direction when air resistance is ignored?
