1. Calculate the average acceleration for each height . Please see " Data " for other average accelerations 2. Using trigonometry and your values of x and h in the data tables .calculate the sine of the incline angle for each height .Note that x is the hypotenuse of a right triangle Please see "Data " for other sine values . 3. Set up a data table in Microsoft Excel for sin (6) in one column and values for the average acceleration in a column to the right of the sin (8) column Please see page 7 for this table . 4. Use Microsoft Excel to plot a graph of the average acceleration on vs. sin (e), on the y and x axes respectively .From the equation determine the slope of your graph .This will be your experimental value for "g". m = gexperimental : 3-9006 mISZ Please see page 7 for this graph . Questions 1. Compare the slope of your Excel graph to the accepted value for "g". 2. What physical experimental uncertainties in the experiment could account of the difference between the calculated and accepted values
