A thin rod sits along thexaxis with one end atx= -aand the other end atx=a, wherea=2.4m. The rod has anon-uniform densitygiven by(x+a)2, where=1.7kg/m3. I already got the total Mass= 62.669, but now I need to find the Center Mass. I got to where the equation is /M*(integral from -a to a) x(x+a)^2 and I can't solve any further
