    Acceleration and Newtons laws
    A 1.1 *10^3 Kg car accelerates at 3.40m/s^2 . If the wheel exerts a force of 5.6*10^3N on the road, calculate the force resisting the motion?

    Here, find the resultant force F.

    Since the forward force is given, and the net force is given, you can find the opposing force.
