SUMMARY
The speed at which a pole-vaulter lands after reaching a height of 6.0 meters can be calculated using the law of conservation of energy. The potential energy at the peak height converts entirely into kinetic energy just before landing. For a pole-vaulter with a mass of 60 kg, the landing speed is approximately 10.8 m/s, derived from the equation v = √(2gh), where g is the acceleration due to gravity (9.81 m/s²) and h is the height (6.0 m).
