A car of mass 1 tonne is towing a trailer of mass 400kg. They are connected by a rigid rod. Initially they are travelling at a constant speed. The car then accelerates. If the force in the rod is 600 N, find the acceleration of the car and the driving force of the engine.

  1. Damon

    600 = 400 a
    so
    a = 600/400

    total force = 400 a + 1000 a
    = 1400 a

  2. Stephan

    And total force is Power of engine-600 ?
