Homework Help: Calculating standard deviation for average force

  1. Feb 20, 2015 #1
    1. The problem statement, all variables and given/known data
    I am stuck on the last problem.
    2. Relevant equations
    Just the error propagation equations

    3. The attempt at a solution
    I initially used the multiplication error propagation formula. So the average force would be the impulse divided by the time, the same thing as the impulse times 1/time. Favg = Iā‹…1/t. So the deviation for force would be the absolute value of I times 1/(deviation of time)? But this is wrong, as I get 131, a number that wouldn't make sense. How do I find the deviation for Favg? I feel like I might have to use some of my other data.....
