Question

Simple Question

If I have the kinetic friction force and the normal force then what equation would I use to find mu kinetic?

Answer 1

It really depends on the situation. Do you have a diagram? Is it on an inclined plane? Flat horizontal surface?

Answer 2

Sorry for the delay. Yes. I'll send a link to the page in the textbook.

Answer 3

So something like this: https://ia801701.us.archive.org/BookReader/BookReaderImages.php?zip=/11/items/PhysicsPrinciplesAndProblemsByAGlencoeProgram/Physics%20Principles%20and%20Problems%20By%20A%20Glencoe%20Program_jp2.zip&file=Physics%20Principles%20and%20Problems%20By%20A%20Glencoe%20Program_jp2/Physics%20Principles%20and%20Problems%20By%20A%20Glencoe%20Program_0140.jp2&scale=6.979679144385027&rotate=0

Answer 4

Pulling a block with a spring scale. I have Ff and FN, and need to find mu kinetic.

Answer 5

\[\mu_k = \frac{ f_k }{ f_n }\]

Answer 6

As I showed you on your previous post

Answer 7

Ah yes. Thank you. That's what I've been looking for!

Answer 8

Yeah. It gave you the equation in the question -- all you need to do is just solve for the coefficient of kinetic friction

Answer 9

Yeah just had to use a little algebra :P
