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} $

Here is the equation in a more viewable format P*A*C*[VV(t)]^2 = m(dv/dt)

Did you mean PAC(V  v(t))² = 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))²) and integrate, then rearrange the result.
