A new roller coaster is advertised as having a perfectly efficient (energy is conserved) first drop without the presence of an additional applied force. Upon riding this roller coaster, a group of students question whether the roller coaster is actually perfectly efficient and want to design an experiment to test this question. The students hypothesized that inclined surfaces approach perfect efficiency as the surface increases in steepness. Describe the procedure to be used to test the hypothesis in narrative form. Give enough detail so that another student could replicate the experiment. The procedure should include an explanation of how efficiency will be determined/calculated. (2 points)
