B Finding length of an arc produced by projectile

  1. Feb 15, 2017 #1
    So I decided to try deriving a general formula for fun. Being a high school student, the calculus got scary very fast. At this point, I'm just curious as to what the best approach to this might be. The approach I used was finding y as a function of x and then inputting it into the arc length formula. I eventually derived a very complicated formula that I think is wrong. I don't know very much about calculus as everything I've learned about it I've learned through the internet. Would this approach work? Is there a better way? If so what is the correct formula?

    You should post what you've done as homework. It's not possible to help without seeing what you've done.

    Arc length question is best posed as a math question - not physics.
