Thank makes sense! Thank you very much!

So what is the acceleration in it? Is it just 3 because of the bigger box?

This is where I'm confused. How do I find the pseudo force?

The static friction?

Isn't it just a=FM? So if the mass is 3M is it A=F/3M? Or do you do A=F/(Small box + Big box) so A=F/(3M+1M)?

I am applying it on the larger box. A diagram the question shows can be found here: http://s3.amazonaws.com/answer-board-image/03f392f4f851dd431c2243239c1a02af.jpg

Homework Statement Two boxes of masses m and 3m are stacked. The surface between the more massive box and the horizontal surface is smooth and the surface between the boxes is rough. If the less massive box does not slide on the more massive box, what is t he static friction force on the...
