   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
   
   Ff=<uFn
   
   3. The attempt at a solution
   this is wat i get so far
   mass = 25kg
   uk= .20
   
   .20<.20x25
   .20<5
   
   is this correct? im confuse coz of how much force you exert on the floor not on the box?
   i need help guys

   What forces does the box exert on the floor?
