A system comprised blocks, a light frictionless pulley, and connecting ropes is shown in the figure. The 9.0-kg block is on a perfectly smooth horizontal table. The surfaces of the 12-kg block are rough, with \mu_k = 0.30 between the block and the table. If the 5.0-kg block accelerates downward when it is released, find its acceleration.
the figure looks like this picture (except M= 5kg):

The Attempt at a Solution
I want to say it is 1.6 m/s^s but I am not sure If I did it right.
I just added the force friction to the force tension and then divided by the weights (9+5).
Not sure if this is correct or not.
