a) Start the simulation software. Set M2 to 50 g and M1 to 70 g (M2 must be set first). Hit "Start" to run the simulation. Select the raw data and copy it to your favorite math package (such as Excel). Fit the Position Time data with a quadratic equation (y = Atz + Bt + C). Record the results of your fit here: Quadratic Curve Fitting Parameters A = = By comparing the above fit with the kinematics equations, what is the measured acceleration of the system, a = How does this measured acceleration compare to the calculated acceleration for this mass distribution
