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...
