Deliverable The assignment is to write a Discussion about an angle of slip experiment. Watch video 3.5 Surface Dependence of Friction which demonstrates an angle of slip experiment for a brass block on four different flat surfaces. Estimate and choose an uncertainty in the slip angle using any reasonable criterion you can justify (might it seem likely to be repeatable to within 2"? 507 10"?) Use an upper/lower bound analysis to determine the uncertainty in the static coefficient of friction for each surface. Characterize your results and their uncertainties in a consistent fashion with respect to sig figs. Note: this bullet is the analysis that is required to write the discussion. When you are done with the analysis, write a Discussion based on the analysis. This assignment is about analyzing and then discussing the experiment in the video alone; however, inform what the experiment is about and how you might estimate the uncertainty in the angle of slip
