y-coord of center of mass for region between f(x) = 2 sin(2x) on 0 <= x <= pi/2

[cheejudo]

Can someone please help explain the problem?

5) Determine the y-coordinate of the center of mass for the region between the function \(\displaystyle f(x) = 2 \sin(2x)\) on \(\displaystyle 0\leq x \leq \frac{\pi}{2}.\) Use \(\displaystyle \bar{y} = \frac{M_x}{mass}\)

2) Just exactly where did you attempt to calculate \(\displaystyle M_{x}\). Please demonstrate your calculation, here.
