1. Air Cart on Pulley Experiment: a. Draw the free body force diagram of the dangling mass (m2), when you are holding the system at rest. Be sure to label your coordinate system, to set up Fnet ma in the next step. Air cart F hand m Pulley m Mass b. Draw the free body force diagram of the air cart (m), in this same configuration where you are holding the system at rest. Again, label coordinate axes. c. Write the three equations of Newton's Second Law for the two masses (x-component, y- component for the air cart and one equation for dangling mass) with proper signs for directions. Be clear about which equation corresponds to which object, and which direction.
