Quizplus · Accepted Answer

The minimum energy required is calculated using the formula for gravitational potential energy: E = mgh, where m is the total mass (65 kg), g is the acceleration due to gravity (9.8 m/s²), and h is the height (8,150 m). This gives E = 65 kg * 9.8 m/s² * 8,150 m = 5,192,700 J, or approximately 5.19 MJ.
