Draw a best-fit line by hand or use the linear-regression feature of your calculator or Graphical Analysis and determine the slope. The slope can be used to determine the acceleration of the cart on an incline of any angle. On the graph, carry the fitted line out to sin(90() = 1 on the horizontal axis, and read the value of the acceleration.
