Teach me to fish outward force ball on string

  1. Feb 17, 2009 #1
    I am requesting a precise step by step calculation for the outward force of a 2 pound ball on an 18 inch string being spun at 2000 rpm.

    I know it's F = M times V squared devided by radius; but I must be excluding something important in the formula.

    I need it to learn the math for a project. If u will show me each step using english measurements I would be very thankful.

    Yes that did help in that I used the form to do math. However I'm not allways on the net; I have not yet, "learned" to fish. If someone would like to take the time to work the full math out providing me with a sample including clarification of each move, I would greatly appreciate it and gladly take it from there.. However I am thankful for ur help as I truly can use what u provided at the moment. Also 2 of ur addresses were the same. Did not know if u meant to put 3 up or not.. Once again, thank you.
