Atypical efficiency for human muscles is 20.0%. for instance, when your body metabolizes 100 j of chemical energy it converts this into 20 j of mechanical work (here, climbing stairs), while the remainder is lost to thermal energy. assuming all the energy consumed during exercise comes from burning fat, how many times must he run up the flight of stairs to burn 1.001.00 kg of fat?
