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?
Ff=coeff of kinetic friction (mu k) m*g
?? not sure.
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.
