I am just about to find the co-efficient of friction from my experimental results, and from the equation I cant get past this bit. how do I calculate the co-efficient of friction from or which way do I re-arrange the equation so I can find n, the co-efficient of friction?

11000=12184/9n

Silly question innit!

$$11000=\frac{12184}{9n}$$

Multiply both sides by n

$$11000n=\frac{12184}{9}$$

Divide both sides by 11000

$$n=\frac{12184}{(9)(11000)}$$
