Homework Help: Stuck on intergration

  1. Oct 13, 2004 #1
    i have a force acting on and object and i've gotten the question down to when i have to intergrate but i'm stuck on the intergral
    [tex] F=-(f+cv^2)[/tex]
    [tex] m \frac{dv}{dx} \frac {dx}{dt} = -(f+cv^2) [/tex]
    f and c are constants
    [tex] mvdv=-(f+cv^2)dx [/tex]
    [tex] \frac{mvdv}{f+cv^2}=-dx [/tex]
    now how do i intergrat them from [tex] v_{o} to 0 and 0 to x [/tex]

    This is the kind where the numerator has to be expressed as a constant times the derivative of the denominator. Find the constant and you're through. Simply put, differentiate the denominator and observe the similarity with the numerator.
