Problem:

A 1.00 x 10⁴newton car is traveling down a straight, level road at a constant speed. If the combined forces of friction acting on the car have a magnitude of 1.20 x 10² newtons, what is the magnitude of the force propelling the car forward?

Definition Definition Force that opposes motion when the surface of one item rubs against the surface of another. The unit of force of friction is same as the unit of force.
