The discussion centers on calculating the time of free fall for an object with an initial velocity. The correct equation to use is derived from the quadratic formula: (1/2)gt² + vit - h = 0, where g represents gravitational acceleration, vi is the initial velocity, and h is the distance fallen. The initial equation √(2 ⋅ h / a) is only applicable when the initial velocity (vi) is zero. Thus, for objects in motion, the quadratic equation must be utilized to accurately determine the time of fall.
