Two boxes (m1=27.0kg and m2=12.0kg) are connected by a light string that passes over a light, frictionless pully. One box rests on a frictionless ramp that rises at 30.0 degrees above the horizontal, and the system is released from rest.
a) Either on the figure above or on your own diagram, show the forces acting on each of the boxes.
b) Find the acceleration of each box, stating clearly which direction each box will move.
