Question

sorry, here it is...

Suppose that Dwight has a potential to be a superman who can use the maximum of 90% of his body potential. Dwight is NOW boxing with exactly this efficiency and is metabolizing the same of energy. Find the new amount of work done by Dwight. Find the ratio of the work done by Dwight to the one in part a. (e.g. Wb/Wa?) (b) amount Ant ps. Suppose that the work done is proportional to a force strength (W α F). The ratio you found in part (b) would show how many times stronger Dwight's punch is, if he can exercise with 90% of his efficiency. Imagine what will happen to his opponent in a boxing match! (c) Following part (a), find the total change in entropy for this workout process. If Dwight's body temperature is 38°C and the room temperature is 20°C. Does your result validate the 2nd Law of Thermodynamics? 3. A local student Dwight is hitting a boxing sandbag and metabolizing 1200J 8F HI n li transferred out of Dwight's body is 950 J. Assume that Dwight's body temperature stays constant and no food is taken in this workout process. (a) Find i) the work done by Dwight, and () his body efficiency.
