Why is the actual time interval is longer than the interval you have calculated in part one?

The actual time interval is often longer than the calculated interval due to various factors such as measurement inaccuracies, unaccounted variables, or assumptions made in the calculations that do not hold true in real-world conditions. Additionally, external influences like friction, air resistance, or changes in environmental conditions can also contribute to discrepancies. These factors can lead to delays or variations that extend the time beyond theoretical predictions.
