Homework Help: Linear Momentum question.

  1. Oct 17, 2006 #1
    Hello.
    I need confirmation on simple linear momentum questions...

    1. two cars on the surface. car A approaches to car B at Va while car B is at rest. masses of both cars are same. which car puts more force or is it same?
    Car A exerts larger force on B
    Car B exerts larger force on A
    Same

    2. truck is towing the car. when the truck is accelerating, does...
    the car exerts larger force on truck
    the truck exerts larger force on car
    same

    just these 2 questions...if you can help me out. thank you.

    equan and opposite force according to third law...
    so both questions's answers are same right?

    No need to think about momentum. Think Newton and his 3rd law.
