Normal force problem

  1. Oct 31, 2008 #1
    1. The problem statement, all variables and given/known data
    An airplane is taking off at an acceleration of 3.5 m/s2at an angle of 45 degrees relative to the horizontal. Find the Normal force and its direction that is acting on the pilot if the mass of the pilot is 50 kg.



    2. Relevant equations



    3. The attempt at a solution

    Fg = FNy
    (50)(9.8) = FNy
    FNy = 490 N

    Since there is an angle of 45 degrees, FNy = FNx, So FNx = 490 N

    FNx2 + FNy2 = FN2

    FN = 692.96 N at an angle of 45 degrees west of north.

    Do you think the acceleration of the plane will affect the normal force?

    (And be careful when quoting your angle at the end!)

    The pilot gets 2 forces from accelerations: gravity and takeoff. Also, this won't be a compass direction problem, it will be a left/right up/down problem.
