Suppose a car travelk 433 km at a speed of 51.25 m/s, and uses 3 gal of gasoline, Only 34 % 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 1.2 x 10' J/gal.) a) What is the force exerted to keep the car moving at constant speed? 282678983.8 N b) If the required force is directly proportional to speed, how many gallons of gasoline will be used to drive 433 km at a speed of 20.5 m/s? gal Suppose a car travelk 433 km at a speed of 51.25 m/s, and uses 3 gal of gasoline, Only 34 % of the gasoline goes into useful work by the force that keeps the car moving at constant speed despite friction.
