Does this question even make sense: A 7900 kg helicopter carrying a 1100 kg load is accelerating upwards at 1.2 m/sec squared. What is the force of air resistance pushing down on the helicopter?

  • physics -

    not unless you know something about the force pushing upward.

    net force F = ma
    Forceup - forcedown = (7900+1100)(1.2)
