Homework Help: Vertical Circle

  1. Oct 25, 2008 #1
    1. The problem statement, all variables and given/known data
    A 9940 kg plane in an air show completes a vertical loop of radius 596 meters at 155 m/s. What normal force does the airplane seat exert on the 92 kg pilot at the top of the loop and at the bottom of the loop.

    2. Relevant equations

    Top of loop
    m(v^2/r)= Fnormal + mg
    m(v^2/r)= Fnormal - mg

    3. The attempt at a solution
    should i use the mass of the pilot and the plane for this problem iam really stuck.

    Hi myoplex11,

    It's asking about forces acting on the pilot, so begin with a free body diagram for the pilot. What mass would you use? What forces act on the pilot, and what is the pilot's acceleration?
