Differential equation problem!

How do i work this differential equation out so that it is in the form "v(t)= ... " I'm afraid that i am a bit rusty at DE
$\displaystyle
\rho A C_D (V_w - v(t))^2 = m \frac {dv} {dt}
$

Re: Differential equation problem!

Here is the equation in a more viewable format

P*A*C*[V-V(t)]^2 = m(dv/dt)

Did you mean PAC(V - v(t)) = m(dv/dt), where V and PAC/m are constants? If so, separate the variables (i.e., divide the equation by m(V - v(t))) and integrate, then rearrange the result.
