Homework Help: Centripetal Force (Loop the Loop)

  1. Sep 18, 2008 #1
    1. The problem statement, all variables and given/known data
    A pilot, whose mass is 78.0 kg, makes a loop-the-loop in a fast jet. Assume that the jet maintains a constant speed of 105 m/s and that the radius of the loop-the-loop is 0.562 km. What is the apparent weight that the pilot feels (i.e., the force with which the pilot presses against the seat) at the bottom of the loop-the-loop?

    2. Relevant equations
    F = m(V^2/R)

    3. The attempt at a solution

    F = 78 (105^2/562)
    F = 1530.2 N

    n = m(g + v^2/R)
