I have to find the coefficient of friction between the bookcase and the ground, this is all that I was given, there is no angle. I am assuming that this is a flat surface.
Homework Statement
what is the coefficient of friction between a 41N bookcase and the groud, when the bookcase accelerates at .25m/s2?
Homework Equations
F=ma Forcefriction=μ*force normal
The Attempt at a Solution
a=.25 m=41 μ=? I have absolutly no idea what i am doing
