Question: A 9410-kg car is travelling at 28.7 m/s when the driver decides to exit the freeway by going up a ramp. After coasting 397 m along the exit ramp the car's speed is 11.8 m/s, and it is h = 11.3 m above the freeway.
Part A: What is the magnitude of the average drag force exerted on the car?
I want help to find the magnitude of the average drag force exerted on the car.
