Question: how to find the time in a free fall?
Answer: 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 + g * t = 0 + 9.80665 * 8 = 78.45 m/s . Find the free fall distance using the equation s = 0.5 * g * t² = 0.5 * 9.80665 * 8² = 313.8 m .
