Determing Acceleration, Tension

  1. Mar 24, 2009 #1
    1. The problem statement, all variables and given/known data
    I had a wheel.
    I hung five weights of known masses from the wheel, and these fell a known distance in a known time.
    I also hung a weight and added mass until it just began to move, so I know the frictional force the wheel must overcome to spin.

    I feel so silly asking it, but how can I find
    the acceleration of the falling masses?
    the tension in the string?


    2. Relevant equations



    3. The attempt at a solution

    Hi Oijl:smile:
    You can get the acceleration from the time and distance by using one of the standard constant acceleration equations.

    And the tension in the string, when it isn't accelerating, will just be mg. :wink:
