Finding force of friction with only applied force and acceleration given?

  1. Mar 10, 2009 #1
    1. The problem statement, all variables and given/known data
    What is the value of the force of friction?
    Acceleration = 1m/s^2
    Applied force = 5.5N

    2. Relevant equations

    3. The attempt at a solution

    I know what to do if mass or a coefficient of friction were given, but unfortunately they're not!

    Any help will be appreciated...
