SUMMARY
The discussion focuses on calculating the speed of a 65kg diver upon hitting the water after diving from a height of 10 meters. The key equation to use is derived from the principles of physics, specifically the equations of motion under constant acceleration due to gravity. The diver's final speed can be calculated using the formula: v = √(2gh), where g is the acceleration due to gravity (approximately 9.81 m/s²) and h is the height (10 m). This results in a final speed of approximately 14.14 m/s upon impact with the water.
