The strings are attached to masses, which you can alter. Your task is to measure the experimental value of the accelerations and compare those values with the results obtained using Newton's Laws. You will calculate the acceleration of the masses below. How does the acceleration of one mass compare to the acceleration of the other mass? Before you begin, review the example above and make sure you know how to predict the acceleration of the system for masses M1 and M2. The description on the previous page explains the derivation of the motion. Derive that expression here. Use M1 = 70 g and M2 = 50 g and determine the acceleration of the system in m/s. NOTE: the larger of these masses is M1 as opposed to M2 in the example above, so the system will move in the other direction
