SUMMARY
The equation for time in parabolic motion is correctly expressed as t = (v - u) / a, where v is the final velocity, u is the initial velocity, and a is the acceleration. The discussion highlights that when the final velocity along the y-axis is zero, the user may be overlooking the need for a negative sign in the equation, indicating a downward motion. Additionally, the possibility of non-constant acceleration is raised, which could further complicate the calculation of time.
