WebFeb 13, 2024 · Decide whether the object has an initial velocity. We will assume v₀ = 0. Choose how long the object is falling. In this example, we will use the time of 8 seconds. Calculate the final free fall speed (just before hitting the ground) with the formula: v = v₀ + gt = 0 + 9.80665 × 8 = 78.45 m/s. Find the free fall distance using the equation: http://hawsedc.com/engcalcs/Manning-Pipe-Flow.php
