Answer:
minimum amount of energy required is 8.673 MJ
Explanation:
given data
mass m1 = 80 kg
additional mass m2 = 20 kg
height = 8850 m
to find out
minimum amount of energy required
solution
we know here total mass is m = m1 + m2
m = 80 + 20
m = 100 kg
so now apply energy equation for climb high that is
energy = m×g×h ....................1
here m is mass and g is 9.8 and h is height
put here all value in equation 1
energy = m×g×h
energy = 100 ×9.8×8850
energy = 8673000 J
so minimum amount of energy required is 8.673 MJ
