Homework Help: How to get the force?

  1. Aug 27, 2012 #1
    1. The problem statement, all variables and given/known data
    you push a 25 kg box across a wooden floor at constant speed. how much force do you exert on the floor? (mu(k) = 0.20

    2. Relevant equations


    3. The attempt at a solution
    this is wat i get so far
    mass = 25kg
    uk= .20


    is this correct? im confuse coz of how much force you exert on the floor not on the box?
    i need help guys
