    1. The problem statement, all variables and given/known data
    Calculate the acceleration of a ball rolling down an inclined plane and also note the error.
    I am going to solve it myself, so I will just give one sample.
    Distance covered by ball(error : +- 0.05 cm)
    .95m
    Time taken(error : +- 0.01 s)
    1.19s
    Acceleration(with error)
    Have to calculate

    2. Relevant equations

    a=2S/t2

    3. The attempt at a solution
    I tried doing .95/1.19, thats change in velocity upon time, but that doesn't include the errors that way.
    Someone please tell me of an easy way to solve this.

    Your error analysis will be done separately. It will depend on how your want to analyze your errors (i.e. in quadrature, etc.). You have solved for acceleration (although you missed ^2 on your time). Now solve for the error and your golden!
