Equilibrium Newton's law

  1. Jul 26, 2007 #1
    1. The problem statement, all variables and given/known data
    A man pushing a piano with a mass 160kg at constant velocity up a ramp that is inclined at 36.9 degrees above the horizontal. Neglect friction. If the force applied by the man is parallel to the incline, calculate the magnitude of this force.

    2. Relevant equations

    3. The attempt at a solution
    summation of Fx = wsin(alpha) - Fman = 0
    Fman = (160kg)(9.8)(sin(36.9))
    = 941N
