2 . Write out the final answer for the coefficient of friction as the average of the values in the table (average all of your coefficients of frictions, and write that average below). Show your work.

3. Using similar methods as in questions #1 and #2, estimate the mass of the object in the present, the mystery mass. Include a description of the process and the mathematics of estimating the mass. Use the average coefficient of friction written in #2 to solve for the mystery mass. Show your work
