None of the above

Explanation:
Detailed explanation-1: -Initial velocity describes how fast an object travels when gravity first applies force on the object. On the other hand, the final velocity is a vector quantity that measures the speed and direction of a moving body after it has reached its maximum acceleration.
Detailed explanation-2: -Final velocity (v) squared equals initial velocity (u) squared plus two times acceleration (a) times displacement (s). Solving for v, final velocity (v) equals the square root of initial velocity (u) squared plus two times acceleration (a) times displacement (s).
Detailed explanation-3: -v = u + at. v² = u² + 2as. s = ut + ½at²
