I have to following differential equation. I need to solve it. I have gotten so far but got stuck... I have tried solving the equation using seperation of variables, which I think is where I've gone wrong. This is the equation:

$\displaystyle v\frac{dv}{dx}=-\frac{g}{10}(2+3v)$

Is seperation of variables the way to go, i.e, should I start by dividing through by:

$\displaystyle (2+3v)$
