Example 1: How far can a car travel at 70 mph
on one liter of gasoline if:
One liter of gasoline contains 40 million Joules.
The engine is 100% efficient.
The air resistance and friction at 70 mph is 500 N.
Work = (Force)(distance) d = W 4 x10 7 J
= 0.8 x10 5 m = 80 km
F 5 x10 2 N Adiabatic Processes
