If you exert 28N of horizontal force while pushing a 10.2 kg box across the surface of a floor at constant velocity, then what is the kinetic friction coefficient between floor and the box?

2. Relevant equations

EF = ma

Ffk = uK * Fn

3. The attempt at a solution

Fg = 10.2 * -9.8 = -100 = 100 = FN

Ef = ma

28N + Ffk = 10.2 * 0 m/s^2 (constant velocity)

Ffk = -28N

uk = -28/100 = -.28 coefficient is this correct?
