What average mechanical power (in W) must a 61.5 kg mountain climber generate to climb to the summit of a hill of height 365 m in 41.0 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. Use the general work-energy theorem to find the climber's work and substitute into the definition of average power.
