An advertisement shows a 1239 kg1239 kg car slowly pulling at constant speed a large passenger airplane to demonstrate the power of its newly designed 63.7 hp63.7 hp (horsepower) engine. During the pull, the car passes two landmarks spaced 25.0 m25.0 m apart in 14.3 s.14.3 s. The passenger plane being towed is a Boeing 707 with a total weight of 62.5 tons.62.5 tons.
Calculate the force that opposes the motion. Assume that the efficiency of the car is such that 24.2%24.2% of the engine power is available to propel the car forward. How much work is performed by the car on the airplane during this time?How much work is performed by the airplane on the car during this time?
