Assignment:
A car requires a total of C liters of gasoline to drive 10 km on a flat road at constant speed. After installing new tires on the car, the rolling friction coefficient between the tires and the ground increases by a factor of 2 with respect to the old tires*. How much gasoline will the car need to complete the 10 km at constant speed using the new tires? Assume only rolling friction causes the car to lose energy (and all other friction forces are negligible).
