ok, our class got an assignment where we have to derive an equation for coefficient of static friction between our text book (inclined at an angle theta) and a coin. The vale of the angle and the mass of the coin are not given. I have come up with the following equation and need to know if it is correct.(adsbygoogle = window.adsbygoogle || []).push({});

u = Ff(static)/Fnormal

*using components of the force of gravity, i determined Ff to be FgxSINxTheta and Fnormal to be FgxCOSxtheta

so,

u = FgxSINxTheta/FgxCOSxtheta

does this seem correct?

thanks for looking.
