Given data
*A box weighs is N = 51.1 N
*The applied force is F = 6.30 N
The formula for the coefficient of friction between the box and the floor is given as
[tex]\mu=\frac{F}{N}[/tex]Substitute the known values in the above expression as
[tex]\begin{gathered} \mu=\frac{6.30}{51.1} \\ =0.123 \end{gathered}[/tex]Hence, the coefficient of friction between the box and the floor is 0.123
