SUMMARY
Both a 2000 kg vehicle and a 13000 kg vehicle can utilize the same skid-to-stop formula, demonstrating that weight does not significantly affect the stopping speed when using the formula provided. The calculations show that both vehicles, despite their weight difference, achieve a stopping speed of approximately 61.14 km/h when the skid distance is 21 meters and the drag factor is 0.7. The kinetic energy approach confirms that the stopping speed remains consistent across different vehicle weights under these conditions.
