2 heavy washers with closely matched masses

Procedure: The pulley was hung from a doorway and the wire weight hangers hung from it. Two large washers were placed on each hanger. A small washer was added to one side. This heavy mass was held at a measured distance above the floor and let go. A stopwatch was used to determine the time elapsed until it stopped. This step was repeated 5 times. Another small mass was added and the measurements repeated until five sets of data were obtained. The results were recorded in a table. The five values for average acceleration were plotted as a function of the quantity (m1-m2)/(m1+m2) and a line of best fit was drawn through the points. The slope of the line was determined and the value for g calculated.
