Car pushing on truck

  1. Feb 21, 2009 #1
    1. The problem statement, all variables and given/known data

    A 1000 kg car pushes a 2000 kg truck that has a dead battery. When the driver steps on the accelerator, the drive wheels of the car push against the ground with a force of 4500N . Rolling friction can be neglected.

    What is the magnitude of the force of the car on the truck?

    2. Relevant equations

    3. The attempt at a solution

    I thought it would be 4500N but its not

    The 4500N force is needed to accelerate both the car and the truck.

    What portion of that is needed to accelerate just the truck?
