Solved: A 52-kg mountain climber, starting from rest,
Chapter 15, Problem 15.106(choose chapter or problem)
A 52-kg mountain climber, starting from rest, climbs a vertical distance of 730 m. At the top, she is again at rest. In the process, her body generates 4.1 106 J of energy via metabolic processes. In fact, her body acts like a heat engine, the efficiency of which is given by Equation 15.11 as e W/QH, where W is the magnitude of the work she does and QH is the magnitude of the input heat. Find her efficiency as a heat engine. Problem
