Homework Equations
Newton's Laws of Motion, gravitational force is mg, and the redirection of force on an inclined plane.
The Attempt at a Solution
In the picture above--basically, I just am not sure how the force of the mass is directed on the plane. I think I get the rest of the important stuff: The acceleration of the system is a, so you can use F = ma since it will only accelerate in the horizontal direction, and each individual object will also have that same acceleration, etc.
