    2. Suppose a car travels 108 km at a speed of 20.0 m/s, and uses 2.20 gallons of gasoline. Only 30% of the gasoline goes into useful work by the force that keeps the car moving at constant speed despite friction. (The energy content of gasoline is 1.3 ✕ 108 J per gallon.) (a) What is the force exerted to keep the car moving at constant speed? N (b) If the required force is directly proportional to speed, how many...
