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. Regards M.K.
