Question

an 80kg mountaineer climbs a 3000m mountain in 10h. What is the average power output during the climb

Answer 1

70 W

Step-by-step explanation:

Power = work / time

P = mgh / t

P = (80 kg) (9.8 m/s²) (3000 m) / (36000 s)

P = 65.3 W

Rounding to one significant figure, the average power output is 70 W.
