Homework Help: Angular momentum sum

  1. Apr 30, 2007 #1
    The sum is a horizontal rod of mass m, len l is pivoted at one end so that it is free to rotate about a vertical axis...and a steady force fo F units acts at the free end, maintaining a direction perpendiculat to the rod. Wat is the work done by this force during the time tat the rod takeds to complete one turn, assuming that it starts from rest?
    i kno its silly to ask this question but still.....pls answer

    Consider the definition of work as a force acting through a distance. Over what distance does the applied force act as it completes one turn?
