Homework Statement
An object experiences a friction force, Ff, of 6.6 N and a normal force, Fn, of 30.0 N.
a) What is the coefficient of friction, μ?
b) Is the object moving? How do you know?
Homework Equations
μ = Ff / Fn
The Attempt at a Solution
I understand how to get the answer for a) which is 0.22:
μ = Ff / Fn
μ = 6.6 / 30.0
As for b) though, I don't know if I'm overthinking it or something, but I think there aren't enough given variables to answer the question. The textbook points out that the question is K/U (in other words, it should be easy) but I can't figure it out.
Thanks in advance.
