Homework Statement
find the mass of an unevenly distributed bar with length 2 meters whos mass at a point is given by an equation 0.6 + x^2. Then find the center of mass.
Homework Equations
The Attempt at a Solution
I got the first part (finding the mass) correctly, but I can't conceptually figure out why what i did to find the center of mass doesn't work.
integrate to get 0.6x + x^3/3 and evaluate from 0 to 2, to find that the mass is 2 kg.
What I tried to do to find the center of mass is just set that equation equal to half the mass and solve for X, however this is not correct and I do not know why...
