Homework Help: Friction homework

  1. Jun 28, 2014 #1
    1. The problem statement, all variables and given/known data: friction.png In the diagram,the coefficient of friction between the bigger block and the smaller block is μ1 and the coefficient of friction between the bigger block and the ground is μ2. Calculate the acceleration of the bigger block.(As seen in the diagram,M is the mass of the bigger block while m is the mass of the smaller block.

    2. Relevant equations: F = ma

    3. The attempt at a solution: I have absolutely no idea about the question,so I need help.

    Can you make a bigger diagram? It's very difficult to look at it

    Just right-click on the diagram and select "Open in new tab". That'll do the trick.

    Usually, the first thing to do in such cases, is to draw all the forces involved. Can you do that?

    Yeah,I know how to draw a FBD.

    Better get started then ;)
    Just be careful, there are several forces in this problem that I would think are very easy to forget about ...
