Homework Help: Error Calculation

  1. Feb 3, 2010 #1
    The problem statement, all variables and given/known data

    Derive an equation for the error in acceleration given the following formula: [tex]a = 2h/t^{2}[/tex]

    where a is acceleration, h is height, and t is time.

    The attempt at a solution

    I was able to come up with the following error equation for acceleration:

    [tex]\delta a = a(\delta h/h) + 2t^{2}(\delta t/t)[/tex]

    Is this correct?

    Thanks

    Well I assume you've experimentally found height and time. so put the error of height in percentage of the height. and then there is a formula i cant remember for error of something squared. but find that, but it in percent as well. then all under a square root, add the square of your errors. then you will have a percent error of acceleration

    The thing is that I'm not looking for percent error, I'm looking for [tex]\delta a[/tex]
