please could i have help with the question attatched
it is about centre of gravity.
thanks
Cut your figure into two pieces. (a square and a triangle)
You can easily find the coordinates of the center of mass of the square using symmetry arguments.
You can find the coordinates of the center of mass of the triangle using the definition of the mean
$\displaystyle c_x=\frac{\int x f(x) dx}{\int f(x) dx}$
$\displaystyle c_y=\frac{\int y f(y) dy}{\int f(y) dy}$
Then you can find the center of mass of the whole thing with
$\displaystyle *MR = m_1r_1+m_2r_2 $*r being the vectors of position.
