At the highest point of the path of a projectile, its velocity is
- A. zero in every direction
- B. horizontal only, with the vertical component zero
- C. vertical only
- D. equal to the launch velocity
Explanation
Gravity acts only vertically, so the horizontal component of velocity is unchanged throughout the flight while the vertical component falls to zero at the peak. The projectile is therefore still moving horizontally at the top, which is why its acceleration there is still g downwards even though the vertical velocity is momentarily zero.
