Coefficient of friction on an inclined plane

[QUOTE="Simon Bridge, post: 4514917, member: 367532"] It will be obvious from the way you substituted the expressions for the forces into ƩF=ma. The final expression need not be in that form. Work through the derivation first, see where that leads you. Note: 30deg is a very nice angle. sin(30)=1/2 cos(30)=(√3)/2 tan(30)=1/√3 ... use the RHS versions [i]without[/i] converting to decimal. Your problem statement does not give the angle of the incline however. ... where did you get 31deg from? Apart from that you appear to have answered your own question (above). In your case it turned out that x=1. [/QUOTE]
