Help with this mechanism (acceleration with graphic method)

[Noob of the Maths]

Homework Statement

Find the aceleration of each link in the mechanism

Relevant Equations

W = V´2/r

Hi guys!
I have problems with this mechanism...finding the aceleration with graphic method.

I already have drawn the speed diagram and the values of all of them.

But, i dont know if my aceleration diagram it is well drawn. I'm stuck especially when trying to plot and calculate the acceleration of "G"
