2 Masses, Friction, Inclined Plane, Pulley problem

Here's a problem I've been having trouble with. I was hoping someone out there can give me some insight on it. Basically it's just two masses both coupled together with a massless rope on a frictionless and massless pulley on an inclined plane WITH friction. Here's the diagram. The problem is to figure out the tension in the rope and the acceleration of the blocks.

Well, use Newton's 2nd Law, and pick a direction for the acceleration.

[tex] \sum_{i=1}^{n} \vec{F}_{i} = m \vec{a} [/tex]

Also remember

[tex] F_{f} = \mu N [/tex]

you get two dynamical equations... In which there are only two unknowns... Tension and acceleration..... frictional force is known... Two equations two variables...Voila ! Theres your answer
