I am working on a Friction lab for my physics class, I will attach my data and graphs. My experimental coefficient of kinetic friction is 4.375, which gives me a minimum angle (theta) = 77 degrees, which is really far off (experimentally 9.5 degrees). Have I done something incorrectly? The data is from my instructor (through a video). Thank you.
