Absolute/Percent Uncertainty Help

  1. Sep 1, 2010 #1
    1. The problem statement, all variables and given/known data
    In case A on the left the ball is on a string. The ball is measured at 3.3 inches In case B on the right the ball is on a very sensitive spring. The ball keeps bouncing up and down, reaching the extremes. The low extreme is about 3 inches, the middle is 3.5 inches, and upper extreme is 4 inches

    I am trying to find the absolute uncertainty and percent uncertainty on both case A and but there are some parts that I am not sure what to do

    2. Relevant equations

    Absolute uncertainty:refers to the actual uncertainty in a quantity

    Percent uncertainty:

    (uncertainty / value) x 100 =

    3. The attempt at a solution

    for finding percent uncertainty on case A
    (0.3/3.3) x 100 = 9.09%

    I am confused on what to do afterwards
