When an automobile moves with constant speed down a highway , most of the power developed by the engain is used to compensate on the car by the air and the road, friction forces exerted on the car by the air and the road. If the power developed by an engine is `175 hp`, estimate the total friction force (apporox) acting on the car when it is moving at a speed of `25 m//s`. One horsepower equals `746 W`.
