How many days of a diet of 1910 large calories are equivalent to the gravitational energy change from sea level to the top of Mount Everest, 8848 m above sea level? Assume your mass is 53 kg. (The body is not anywhere near 100% efficient in converting chemical energy into change in altitude. Also note that this is in addition to your basal metabolism.)

Ответ:
0.58 days is needed
Explanation:
Gravitational energy change from a height change equal to 8848 m for a mass of 53 kg is:
m*g*h = 53*9.81*8848 = 4600340.64 J = 4600.34 kJ
4.184 kJ are equivalent to 1 kcal, then:
4.184 kJ / 4600.34 kJ = 1 kcal / x kcal
x = 4600.34/4.184
x = 1099.5 kcal or large calories
The diet is 1910 kcal/day, then you need 1099.5/1910 = 0.58 days
