Hey,(adsbygoogle = window.adsbygoogle || []).push({});

I'm terrible with fractions and would appreciate any help regarding this problem.

This is a problem from my physics course.

F2 = [ (v + v2)/(v + v1) ] F1

I need to solve for v1. I am given the values for F2, v, v2, and F1 and need to turn the formula around to solve for v1..

F1 = 400

F2 = 420

v = 344

v2 = 26.82

My attempt was F2/(F1(v+v2)) = 1 / (v+v1)

but this is wrong..

any suggestions?
