&quot; Find the specified data file in LoggerPro of cart masses and acceleration. Use the modeling techniques you
learned in lab to find a mathematical model describing the dependence of acceleration of the cart on the cart's
mass. Write down your model equation and provide a physical interpretation of the parameter(s). Sketch your
graph and label the axes.&quot;(4&quot;pts)
