2.) An Atwood machine experiment generates the following data. 0 Find the measured acceleration from this experimental data. Compare the measured value to the expected value. How close are they? Use the curve t to nd Position (m) the experimental value for the acceleration. Curve t to data: 3! = -0.271 x3 + 1.03 x 0.492 * Time (sec) Use these masses to nd the expected value for the m2 = 143.1 g acceleration. m1 = 159.7 g
