Homework Help: Centripetal motion

  1. Feb 12, 2006 #1
    resolved thanks to astronuc... radius = d/2

    i accidentally used the diameter as my radius

    Well, let the period T = 1/f = 4.4 s.

    and f = [itex]\omega[/itex] /2[itex]\pi[/itex]

    and the centripetal force = Fc = m[itex]\omega^2[/itex]r = mv2/r, where r is the radius of the circular trajectory.

    Also don't forget the rider is still in a gravitational field, so don't forget the rider's weight due to gravity, mg, which is always down.
