## Homework Statement

A chain in the shape of [tex]y = x^{2}[/tex] between x = -1 and x = 1, has density of |x|. Find M, and CM.## Homework Equations

## The Attempt at a Solution

[tex]\int^{1}_{-1}|x|dx = \int^{0}_{-1}-xdx + \int^{1}_{0}xdx = 1[/tex]

I got this far and realized that I did nothing with the function itself.

The formulas I've used before deal with masses bounded by curves, not the mass of the curves themselves.
