(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

You use 30N (**Not 25 N, that was a typo) to slide a wooden box that is 12 kg across a floor at constant velocity. What is the coefficient of kinetic fricition?

2. Relevant equations

Ff=coeff of kinetic friction (mu k) m*g

?? not sure.

3. The attempt at a solution

coeff of kinetic friction=12 kg/30N=.4.

That answer is obviously incorrect, but I don't know what to do.

Thanks in advance.
