Physics

3 boxes, having masses m1=5kg, m2=10kg andm3=15 kg are stacked \"sideways\" (i.e., in x-) on a surfacewith coefficient of kinetic friction 0.7muk; an external force of magnitude 15N pushes on the right-most box, making an angle of30 degrees relative to thehorizontal; a second force of magnitude 20N pushes in the opposite direction on the left-most box,as a result of which all three accelerate uniformly. Determine thenumerical value all of the forces acting on each of the boxes(including all normal forces between the boxes), as well as theamount the boxes have moved after a time of 7seconds. Keep in mind that the normal force actingspecifically on the box subject to the external force is changed bythe external force...
