14. Design an experiment to find the Drag force for different speeds to determine whether the linear or quadratic term is most important in this situation. You will want to use Excel to graph your data and fit functions (what kind?) to your data. In designing this experiment, you will need to consider several issues: (a) How will you determine the Drag force on the coffee filter? Why is terminal speed a particularly useful situation for determining the Drag force? (If you had really good acceleration data, you could use the acceleration to determine D before terminal speed, but in this experiment the acceleration data is far too noisy to be useful.) (b) How can you vary the mass of the filter without changing other important properties that need to be fixed (e.g., surface area)? (Why should they be kept fixed?) (c) How will you make sure from your data that the object has reached terminal speed? Could you reach a point where there is so much mass that the filter never reaches terminal speed during your experiment? Might you need to drop the filters from a higher initial height? (d) How often do you need to repeat a measurement (including the one you made in Activity 2) to be confident in its accuracy
