Question
A trombone player stands at the end zone (x = 0) of a football field and begins to play its fundamental tone. Assume the trombone is a half open tube that is 3m long.
How much would the trombone player have to move the slider in cm to play 25 Hz?
I calculated the frequency of the fundamental tone - 28.58 Hz. A previous part of the problem said that the end zone is 300ft.
But..what's with the trombone? How do I quantify the amount of slide? What should I be solving for?

at 3 meters (300 cm) you got 28.58 Hz
What length gives 25 Hz? (a bit longer)
subtract

But how do you relate frequency and length of the trombone together?
