On vacation, your 1400 kg car pulls a 560 kg trailer away from a stoplight with an acceleration of 2.20. What is the net force exerted by the car on the trailer?What force does the trailer exert on the car? What is the net force acting on the car?

    Apply Newton's second law, F = M a, to the trailer to get the towing force on the trailer. In this case, M will be the mass of the trailer.

    The same force will be applied to the car by the trailer.

    Since you know the car is accelerating at the same rate, use F = Ma for the net force on the car. In this case, M is the mass of the car.

    I am not going to answer any more of your questions unless you show some work of your own. Perhaps someone else will help; perhaps not.
