Suppose a car travels 100 km at a speed of 35.0 m/s, and uses 2,00 gallions of gasoline. Only 30% of the gasoline goes into useful work by the force that keeps the car moving att spe despite friction. (The energy content of gasoline is 1.30 x 103 per gallon) (a) What is the force On N) exerted to keep the car moving at constant speed? (b) If the required force is directly proportional to speed; how many gallons will be used to drive 108 km at a speed of 28.0 m/s gallons + Additional Material Reading YOUR TEACHER PRACTICE ANOTHER
