Question: Two boxes (m1 = 42.0 kg and m2 = 35.0 kg ) are connected by a light string that passes over a light, frictionless pulley.

Two boxes (m1 = 42.0 kg and m2 = 35.0 kg ) are connected by a light string that passes over a light, frictionless pulley. One box rests on a frictionless ramp that rises at 30.0∘ above the horizontal (see the figure below), and the system is released from rest.

Part A Which way will the 42.0 kg box move, up the plane or down the plane? Or will it even move at all?

Part B Find the acceleration of each box.
