3. Use Newton's Second Law to write an guation for each of the free body diagrams you drew in Question 2 (use the correct signs to agree with your drawings). These equations should be similar to those found in Pre-Lab Question 2. For both equations, rearrange them to isolate the force of Tension (FT) variable on the left side. Do not insert any numbers yet. 4. Set the two resulting expressions for the force of Tension from Part 1 equal to one another (as long as the string does not stretch, the magnitude of the acceleration in each equation is the same). Replace Fg1 and F92 with M1 and M2, respectively. Rearrange the resulting expression for the acceleration, a, by isolating a to the left side of the equation. You should now have an expression for the acceleration of a_in terms of both masses. ThenI go back to Question 3 and solve for the FT by substituting your expression for the acceleration al into one of the expressions for the Tension (FT). This should result in an expression for the Tension (F1) in terms of the masses. Again, no numbers to plug in here yet. 5. Calculate the acceleration for the two sets of data you recorded using the expression for acceleration you determined in Post-Lab Question 4, and compare these values to those obtained by measuring distance and time using percent error. Cite two factors that may cause discrepancies between the two values. 6. Calculate the Tension in the string for the falling washers for both procedures and for the one where the masses were equal. Use the expression for the Tension derived in Post-Lab Question 4. Show all calculations. From these two values: and the one where the masses were egual, what trend do you observe in the Tension in the string as the acceleration increases? Table 5.
