Answer:

Calculate the total energy consumed during the climb:

Total energy consumed = Energy consumption rate * time

= 40908.8 J/min * 180 min

= 7,384,064 J

Calculate the power consumed in joules per second:

Power consumed (in joules per second) = Total energy consumed / Time taken

= 7,384,064 J / 10800 sec

≈ 683.426 J/s

Therefore, the power consumed during the climb is approximately 683.426 joules per second (J/s).
