Question
What average mechanical power (in W) must a 76.5 kg mountain climber generate to climb to the summit of a hill of height 345 m in 43.0 min? Note: Due to inefficiencies in converting chemical energy to mechanical energy, the amount calculated here is only a fraction of the power that must be produced by the climber's body.
