When it is burned, 1 gallon of gasoline produces 1.3 x 108 I of energy. A 1500-kg car accelerates from rest to 37 m/s in 10 s. The engine of this car is only 15% efficient (which is typical), meaning that only 15% of the energy from the combustion of the gasoline is used to accelerate the car. The rest goes into things like the interns! kinetic energy of the engine parts as well as heating of the exhaust air and engine.
(a) How many gallons of gasoline does this car use during the acceleration?
(b) How many such accelerations will it take to burn up 1 gallon of gas?
