2 more parts to the problem but I dont even know how to begin (;

anonymous · Answer

Let's start with some free body diagrams.

from here we want to think about modified free body diagrams so we can isolate forces in the direction of motion for our system.

We are only concerned with the acceleration of the system in the direction of motion as each object will not move toward or away from the ramps.  So we want the tension forces and components of gravity parallel to the ramp surfaces
