My point was that you just wanted to find an equation to pop the numbers into instead of thinking about what was happening. I understand that you had the right idea and second-guessed yourself and became frustrated, but it's a bad habit (and I saw that a lot in my physics students too) to just try to get any answer that "looks right" by sticking numbers in random equations without understanding what you were doing, and you end up not learning anything or learning the wrong thing. That's all I meant about the "what equation do I use question."

I don't know if you will actually need any of this in whatever field you're pursuing, but if you do, it's worth taking seriously even if it's annoying. :blobheartcat: :hug:
