Rotating pendulum. Find absolute acceleration

1. The problem statement, all variables and given/known data



I have to find current absolute acceleration in attached picture in points 1,2,3,4 and draw vectors.

The picture is rotating pendulum. The rest data show attached picture:





2. Relevant equations



aabs = arel + au + acor



acor=2*angular velocity X vrel



3. The attempt at a solution

This is my first attempt:





My teacher said that it is wrong attempt.
