For one movie, the measured puck positions in pixels at frame 0, N/5, and N are (40, 450), (112, 380), and (600, 150). Calculate the angles of ˆuf inal and ˆuinitial in radians. Using the basic uncertainty estimate of Equation 4 (equivalent to Equation 6 with σr = 0), do the angles appear to be significantly different? Is there clear evidence of a force?
