Tetherball Problem

  1. Sep 6, 2006 #1
    Hi. I know it is rude to have your first post be a question, but I am out of time for this (it is due in an hour), so if someone could help, it would be greatly appreciated.

    UPDATE: I just got the first one. I was accidentally thinking that there were 2 ropes pulling it.
    I have tried 4 times (its an online submition thing) and only have one more shot. Any help would be appreciated.

    What I have tried so far:
    To solve for the angle between the poll and ball:
    Theta=ArcSin(.3/2.3)=7.43 degress

    the rope is the only thing capable of applying a vertical force, so it must take care of gravity entirely. Then you need to figure out what the horizontal forces look like (given the angle, and the vertical force, it's basic triangle trigonometry)
