An advertisement shows a 1239 kg car slowly pulling at constant speed a large passenger airplane to demonstrate the power of its newly-designed 89.7-hp (horsepower) engine. During the pull, the car passed two landmarks spaced 23.0 meters apart in 11.3 seconds. The passenger plane being towed is a Boeing 707, with a total weight of 62.5 tons.

Calculate the force that opposes the motion. Assume that the efficiency of the car is such that 20.9% of the engine power is available to propel the car forward.
