3. Determine the coefficient of kinetic friction: a. Using the relationship from Ff,kinetic = MkFN, rewrite the equation for the coefficient of friction in terms of the frictional and normal forces. Mk b. Use Newton's Second Law to rewrite the frictional force and the normal force in terms of acceleration and mass. Hk = c. Determine the average value of the acceleration due to the frictional force from your graph of acceleration vs time. (You can make a visual estimate from your graph.) af = d. Using the equation from part b and the experimental value from part c, calculate the coefficient of friction. Mk= e. Describe the two surfaces involved in generating the frictional force in as much detail as you can. Surface of phone case or material attached to phone: Stationary surface: 3.
