Okay, so I am writing a lab but I am quite stuck on one question. Using the average force of sliding friction from the data, calculate the coefficient of sliding friction. Average force of sliding friction: 0.32N The equation I used to calculate other static/sliding coefficients was: (FgSinX)/(FgCosX) And X is the value of an angle. I am confused because I don't know if I can use this formula to calculate the coefficient because the average force of sliding friction is not an angle. If I use the average force of sliding friction as an angle I get: (9.8xSin0.32)/(9.8xcos0.32) = 0.006 This does not seem right, anyone have any ideas? please and thanks.
