    im guessing it would be the value of v that would make the denominator equal to 0

    you cant have a denominator of zero right?

    That's weird because even the solution here http://www.xtremepapers.com/papers/CIE/Cambridge%20International%20A%20and%20AS%20Level/Mathematics%20%289709%29/9709_w11_ms_51.pdf ended up \[-5 \log (v-50)+c\] but not \[-5 \log \left(10-\frac{v}{5}\right)+c\]

    um, v cannot equal 50. try evaluating your original expression with v = 50.

    v can be 50, ln(0)=1

    ln (0) = infinity

    even your original function: 1/(10-v/5) what do you get when v = 50?

    http://www.wolframalpha.com/input/?i=1%2F%2810-v%2F5%29 Look what would the integral be at v = 50? v = 50 is a vertical asymptote.

    ln (0) is not infinity either

    infinity is not close enough to negative infinity
