Cant resolve this diferential equation

[Robert Mak]

m\frac{dv}{dt}= mg - kv^{2}

constants: m, g, k.

I tryed and i cant find a solution to this diferential equation.

[rock.freak667]

m \frac{dv}{dt}=mg-kv^2

\Rightarrow \frac{m}{mg-kv^2} \frac{dv}{dt}=1

\Rightarrow \frac{m}{mg-kv^2} dv=1 dt


Able now?

thanks; lol i didnt saw it

The full solution can be found on the Wikipedia article for terminal velocity. http://en.wikipedia.org/wiki/Terminal_velocity
