FFO FC calculated system mass (from slope) _DSCH OF.0 80.000 percent error in calculated system mass horizontal intercept of graph calculated friction force (from intercept) Does the value of the friction force resulting from this calculation lie within the range (calculated value plus or minus uncertainty) for the friction force that you found in Procedure A? & 0x80P 3-10

Additional Questions: descending mass m, and (b) the tension in the string above the ascending mass my. [Remember to include 1. For any one mass difference use Equations (3-6) (a&b) to find (a) the tension in the string above the units. Record those tensions as answers 'a' and 'b' in the blanks below. Indicate which mass difference is being used and show your work in the space below the answer blanks. Ti=mi 19-a) v T2=m2 lgta) 2. One more calculation of the friction force: S=T, -T.. Display your calculation and results below. Again, include units. 3. How do your three values of the friction compare with one another? If the three values differ by "much", why do you think that happened? [Note that all three values should be very small. The differences, ideally, should be even smaller.] 3-11
