Finding the acceleration in this force problem

  1. Nov 21, 2016 #1
    1. The problem statement, all variables and given/known data
    m1 is on a frictionless surface and m2 is on a surface with a coefficient of friction of μ.
    Find the acceleration of the blocks in terms of m1, m2, g, Ѳ, μ

    2. Relevant equations
    ΣF=a*m

    3. The attempt at a solution
    a=m2gsinѲ/m1+m2
    is this correct??

    No. What happened to the friction?

    How would I implement that?

    There is a standard way to proceed.
    For each rigid body in the system, draw a Free Body Diagram.
    Assign variables to all the forces, masses and accelerations on/of each.
    Figure out any relationships between the forces on the different masses, likewise their accelerations.
    Write out the ΣF=ma equation for each body.
