Main Question or Discussion Point

I'm doing a review for my physics final, and it's asking me to find the coefficient. The problem says,

A brick has a mass of 1,2 kilograms. A force of 5.4 N is required to move the brick across the floor with a constant velocity. What is the coefficient of friction?

What is the equation I use to solve this?

Try and use Newton's Second Law.

I'm assuming this is coefficient of kinetic friction?

coefficient = Friction force / Normal force


And when you move at constant velocity, total forces on said object = 0, so can you figure it out from there?
