Once a crate is in motion, a horizontal force of 53 N keeps the crate moving with a constant velocity. Find the coefficient of kinetic friction between the crate and the floor.

Question

anonymous · Answer

$$F _{f} = \mu N$$
$$N = mg$$
$$\mu = \frac{ F_{f} }{ mg }$$
Given $$g = 9.8 m/s^2$$ you would get $$\mu = \frac{ 53 }{ m*9.8 }$$
You're missing the mass of the crate(m).

thank you, i realized the mass was on a different page lol
