Problem: When an automobile moves with constant velocity, the power developed is used to overcome the frictional forces exerted by the air and the road. One horsepower equals 746 W, and one mile is 1609 m.
Part A: If the engine develops 50 hp, what total frictional force acts on the car at 49 mph?
Answer in units of N.
I need help to find what total frictional force acts on the car at 49 mph.
