Calculation of error in mass

    The expression for the slope of a graph of (m1 -m2) versus a is given by m = (m1 + m2 + mp)/g. What is the expression for the error in the mass of the pulley, mp?

    You need to rewrite that in terms of mp, and then use standard error propagation rules for sums and products (for the mg term).

    By the way, is there any chance this is from a 1st year lab at the U of A? I tutor there and have been asked this exact question a couple of times!
