a)
Interpretation:
Energy consumed by an average human per day, which is 2100Kcal,should be converted intowatts.
Concept Introduction:
As per the data given, the inventors tried to compare the output of steam engines as that of the horses.The engine would replace the horses. An average workhorse expends energy at a rate of which is originally defined as 550-foot pounds/second and it means, it could pull 550pounds through a distance in one foot in one sec., whereas in modern unitsTherefore, a modern race car with 2.4-L V8 engine is about 740hp.
b)
Interpretation:
Ratio of horsepower to human power should be derived.
