Homework Help: Physics... URGENT !!!!

Posted by Ashley on Tuesday, November 6, 2012 at 10:38am.

A 66.7-kN car is travelling at 66.5 mph when the driver decides to exit the freeway by going up a ramp. After coasting 418 m along the exit ramp the car\'s speed is 28.9 mph, and it is h = 13.1 m above the freeway. What is the magnitude of the average drag force exerted on the car?

Hint: How is the work done by a non-conservative force such as drag related to the change in the car\'s mechanical energy?
