Finding the acceleration of a block

  1. Apr 28, 2009 #1
    1. The problem statement, all variables and given/known data
    The lower block is pulled on a rope with a tension force of 20N. The coefficient of kinetic friction between the lower block and the surface is 0.30. The coefficient of kinetic friction between the lower block and the upper block is also 0.30. What is the acceleration of the 2.0 kg block?

    2. Relevant equations
    Kinematic equations


    3. The attempt at a solution
    I started to use a kinematic equation but I'm not sure what the next step is.

    Did you draw a free-body diagram?
