    the power developed by a man in riding up a 6 percent grade at a constant speed is 200w. the man and his bicycle have a combined mass of 80 kg. Determine the speed of riding

  • dynamics - ,

    0,06P=Fv=mgv
    v=0.06P/mg

  • dynamics - ,

    F=P/v=mgsinα
    v=P/mgsinα=200/80•9.8•0.06 = 4.25 m/s
