Tension Problem

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

The slop has friction.

Variables: m1=4kg , m2=2kg, m3=8kg
μ (coefficient) = 0.1
α=30°

1. What is the acceleration of the system?
2. Calculate the tension of the rope between m1 to m2 and between m2 to m3.

2. Relevant equations

Newton’s second law and free body diagrams.

3. The attempt at a solution

Two boxes on a slope is new to me (I had experience with one so far). I’d appreciate any help, thank you.
