Finding Force of Friction Help

[physicnoob101]

Homework Statement

ok, so in need to find the force of friction applied onto a model rocket. I dont want the answer, but how to find thr force of friction

Homework Equations

i know that F_f=μ_kF_n
F_n=mg

but i dont know how to find μ_k

What's the situation? Unless your model rocket is sliding across a surface, kinetic friction will not be relevant.

the rocket is using a b6 engines and is being launched into the air.

You want to explore air resistance and drag, not kinetic friction.
