Here is the question. I missed this day in class, so now I'm totally lost. Once I figure out how to get it set up, plugging things in and such won't be a problem I don't think.
Two boxes are stacked on top of each other, each box has a mass of 15 kg. You are pushing on the bottom box with a force of 50 N. What is the acceleration of each box if the static and kinematic coefficient of friction between the box and floor is (i'm not sure how to make the right symbols work, but the letters after the u, which would be a mu, are subscripts) us = 0.45 and uk = 0.25 respectively?
Help setting it up would be most appreciated.
