An 8 kg box is on an incline at 40 degrees from the horizontal. It is attached to a 10 kg box via a rope over a pulley that is on another incline of 50 degrees from the horizontal. Both inclines are frictionless. What is the acceleration of the system and what is the tension in the rope connecting the boxes. (Think of a triangle with one box on one side and the other box on the other side connected by a single rope over a pulley).
