Finding the coefficient of friction

  • #1
What is the coefficient of friction between a 65-kilogram chair and a floor if the chair can be pushed at constant speed with a force of 220 newtons?

My attempt:
Given:
m=65 kg Ffr (force of friction)=220 N
w=mg=(65)(9.8)=637 Fn=637 N
μ=?
μ=Ffr/Fn
μ=220/637
μ≈0.345

Is this right? I honestly don't know what I'm doing so if anyone can help me it would be much appreciated. Thanks!

Everything is correct. Why are you saying you don't know what you are doing?
