Homework Help: Ball spinning around a rod

  1. Feb 22, 2008 #1
    1. The problem statement, all variables and given/known data
    A 4.05 kg object is attached to a vertical rod by two strings as in Figure P6.11. The object rotates in a horizontal circle at constant speed 6.50 m/s.

    (a) Find the tension in the upper string.
    (b) Find the tension in the lower string.

    I have no idea where to begin. Any thoughts?
