[solved] Forces and friction

Hi guys :]

1. Homework Statement
A box (A) slides up a ramp due to the mass of the attached box (B).
Given the acceleration and ramp length, determine the force of tension and force of kinetic friction.


2. Homework Equations
Fnet=ma
Fg=mg

3. The Attempt at a Solution
I only got as far as finding the Fnet by multiplying the combined masses and given acceleration. Where do I go from here?
I don't need numerical values, just.. can someone enlighten me on how I should approach this question, so I can find the kinetic friction and tension forces?

Any help is greatly appreciated, thanks :redface:!

I think kinetic friction is found by multiplying the friction coefficient by normal force. So the normal force must be found. Not really sure about tension.
