    1. The problem statement, all variables and given/known data

    As you ride on a ferris wheel, your apparent weight is different at the top and bottom. Calculate your apparent weight at the top and bottom of a Ferris wheel, given that the radius of the wheel is 7.2 meters, it completes one revolution every 28 seconds, and your mass is 55kg.

    2. Relevant equations

    Any circular motion equations

    3. The attempt at a solution

    I don't even know where to start

    When the circle is below you, Fn - mg - Fc = 0. Where Fn is normal force and Fc is centripetal force.
    Fn - mg + Fc = 0 when the circle is above you.
