Two boxes, one with a mass of 60.0 kg and 118 N of friction force and the other with a mass of 90.0kg and 176 N of friction force, are in contact with one another and at rest on a surface. An 850 N force is exerted on the 60.0 kg box toward the 90.0 kg box. Include a Free body diagram. Calculate: a) the acceleration of the boxes b) The magnitude of the action and reaction forces between the boxes (the force of one box on the other)
