Homework Help: Need help on swing set problem

  1. Jun 26, 2010 #1
    At which point does the person on the swing feel the lightest?

    I'm leaning towards #2 and I'm pretty sure it's #2, but I just need to make sure. I'm not sure if this is correct or not, but I believe the velocity acting on the person (upwards), cancels out the gravity or lowering the effects of gravity, thus weight would be lower [w=m(g)].

    At a general angle θ, what would the components of the force? (one is tangential while the other points toward the center of rotation)

    When you get that, remember that the resultant of the normal force and the component provide the centripetal force FC
