If the linear density is constant, then you can just use the formula , where is the mass, and is the length of the wire. Where would you go from there?
A thin wire is bent into the shape of a semicircle x^2+y^2=4 x>0
If the linear density is 3, find the mass of the wire.
Anyone have a clue how to tackle this problem?
Thanks for your help
