Mark decides to build a cabin cruiser.
After many hours of sawing wood, it is determined that the sawing required a total of 63.0 MJ of energy from Mark and 15.0% of this energy came from protein (at 17.2 MJ/kg), 60.0% came from fat (at 33.1 MJ/kg), and 25.0% came from carbohydrates (at 17.2 MJ/kg).
Determine the mass of protein, fat, and carbohydrates consumed in the process.
