Static friction is the friction that exists between two or more solids that are not moving with a relative speed. To calculate the static friction coefficient we use the formula Fs=us × n where Fs is the static friction , us is the coefficient of static friction and the n is the normal force.
thus the coefficient of static friction will be 5 N÷ 25 N =  0.2
Hence 0.2 is the coefficient of static friction

Answer:

0,2 would be the coefficient of friction.

Explanation:

Remember that the force necessary to move an object over a horizontal surface is the weight of the object multiplied by the coeficient of friction, an the formula is this:

[tex]Friction= u*N[/tex]

Where u is the coefficient of static friction and N is the normal force, or in this case the weight of the object so if we solve for U the formula would be like this:

[tex]u=\frac{Friction}{N}[/tex]

Now we just insert the data we know:

[tex]u=\frac{Friction}{N}\\u=\frac{5N}{25N}\\ u=0,2[/tex]

So the coefficient of friction would be 0.2
