Centripetal Force

  1. Oct 21, 2009 #1
    1. The problem statement, all variables and given/known data

    A swing ride at a carnival consist of chairs that are swung in a circle by 15.0 meter cable that makes a 60 degree angle with a verticle pole. The mass of the chair and the occupant is 179 kg. Determine the tension in the cable. Find the speed of the chair

    2. Relevant equations
    F=(mv^2)/r F=mg


    3. The attempt at a solution

    So you draw a free body digram and the forces in the y are -179*10 and 179sin30 and the forces in the x is 179cos30. The radius is 15sin60. Thats about all i have.

    What about the cable? Does not it act on the chair attached to it?
