Math m1

posted by .

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.

  • Math m1 -

    600 = 400 a
    so
    a = 600/400

    total force = 400 a + 1000 a
    = 1400 a

  • Math m1 -

    And total force is Power of engine-600 ?
