Problem: An 8.10 × 103-kg car is travelling at 24.8 m/s when the driver decides to exit the freeway by going up a ramp. After coasting 404 m along the exit ramp the car's speed is 13.3 m/s, and it is h = 12.5 m above the freeway.
Part A: What is the magnitude of the average drag force exerted on the car?
I need help to find the magnitude of the average drag force exerted on the car.
