Basic forces help

  1. Mar 1, 2012 #1
    1. The problem statement, all variables and given/known data

    Two blocks are sliding down an inclide of an angle θ. The larger block has a wooden surface, with a coefficient of friction of uk. The smaller block M is coasted with Teflon, making frictionless contact with the surface. The mass of the larger block is 4M, and the mass of the smaller block is M. Find the acceleration of the blocks.

    2. Relevant equations

    F=ma

    3. The attempt at a solution

    ((4M)(uk)(g)cos(θ))/(4M+M)

    uk=coefficient of friction

    Is this correct?

    I suspect that the question wants you to assume that the blocks are moving independently down the slope.
