Help with predictions and alternate setup please

\fPre-Lab Slide 4: Making a Prediction about the acceleration of the system. Create a prediction about how you think the acceleration of the cart (m,) depends on how much mass is hanging over the side of the pulley (m2). You have an option to take several runs, where you can change m, and/or m2 to observe how acceleration of the cart changes based on mass. a. As you add more mass to m2 (and keep m, the same), do you expect the acceleration of the system to decrease, increase, or stay the same? b. As you add more mass to m, (and keep my constant), do you expect the acceleration of the system to decrease, increase or stay the same? c. You will be responsible, in the lab, for determining your theoretical predictions for the acceleration of your system, by measuring all the component masses. Pre-Lab Slide 5: Alternate Experimental Setup with Friction You will have an opportunity to make measurements of cart acceleration and tension in the system with friction, by leaving the air track off. a. Draw an updated free body diagram that labels where the friction force is, when the air track is turned off. b. If the cart is at rest with the air track off, without you holding it, and a certain amount m2 hanging over the pulley, describe how you could find the coefficient of static friction of the air track. EX LIGHT 2 c. Describe how you could find the coefficient of kinetic friction through several trials of loading increasing mass onto m2, hanging over the edge of the pulley
