2- A cart moves on a smooth, level track set on a table and is connected by a string over a pulley to a small mass (on a hanger) which hangs over the edge of the table. Draw free body diagrams (FBD) of the cart and hanging masses (ALREADY COMPLETED). Then draw a diagram connecting the two free body diagrams of cart and hanging mass into a system as a whole. Mathematically express the the system mass and net force in terms of the masses of each part of the system. (Ignore friction for the time being. Check that each part of the system has the same acceleration (the “a” in F = m a). To apply Newton’s Second Law to this situation, the system mass (the “m” in F = m a) and the net force on the object (the “F” in F = m a) must be clearly specified.)
