How much mechanical energy is needed for avg size person to climb climb up nine flights of stairs?
The Attempt at a Solution
person is about 80kg
h is about 3 meters per floor for 10 floors = 30m
so at top, when the person stops climbing there is only PE so E=0+80*9.8*30=23520J
isn't this only like 4 kcals? doesn't that seem low?
