5.2 Lab Overview Figure 2 should look like the experimental setup at your lab station. A cart (m ) is attached to a string and placed on an incline. The string goes over a pulley and is attached to a hanging mass (my). You will change the angle of the incline 5 times each time adding more mass to the hanger until the cart is no longer moving up or down the incline and the system is static. You will record the amount of hanging mass and the angle of the incline in the data table provided. You will then use your equation for the unknown mass to make a plot. The slope of the plot should provide an answer as to the value of the unknown mass. pulley string cart hanging mass5.2.1 Free-Body Diagrams For the cart and the hanging mass in the static system (Figure 2), draw a free body dia- gram and write the Newton's 2"d Law Equations in the spaces provided.
