1. The problem statement, all variables and given/known data The Quadratic Equation. I am looking for an example of the quadratic equation being used in any form of engineering, or physics. I am supposed to give an example for my algebra class, but I really don't want to do the "two trains left a station," or "sally jumped off a log." I don't know if there are ANY applications of this in engineering or physics that I could use, as it needs to be basic algebra, but I am hoping. Maybe something simple like [tex]f(w) = 10w^2 + 5x + 25 = 0[/tex], where w is windspeed, and the function is for how many turns an hour a windmill will get... Not sure if something like that exists. My class will let me use an existing formula, or to create an example. 2. Relevant equations [tex]ax^2 + bx + c = 0[/tex] 3. The attempt at a solution Searching, googling, pacing, and asking here. I appreciate any assistance that can be offered.
