    Here is the actual problem:

    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 4500 N.

    (a) What is the magnitude of the force of the car on the truck? (answer should be in N)

    (b) What is the magnitude of the force of the truck on the car? (answer should be in N)

    a.) mc = 1000 kg
    mt = 2000 kg
    F = (mc+mt)*a
    => a = 4500/(1000+2000) = 1.5 ...
