Homework Help: Potential energy problem

  1. Feb 2, 2004 #1
    I am faced with the elliptical equation (f(x)/fmax)^2+(x+d/d)^2=1.
    In this equation, f(x) is the draw force of a bow on an arrow, d is distance,x is displacement of bow string. We are given values of d,fmax,and mass and told to calculate the work done on the arrow, and its maximum range. I have no idea how to go about this because of the form of this equation. Can someone lead me in some direction, any direction?

    move the x term to the right side, then take the square root of both sides. after than you can multiply fmax on both sides and you are left with a nice function.
