I've deliberately disregarded the rest of the problem. My question is about the first-order differential equation I set up based upon the given information.

[tex]m\frac{dv}{dt}=-mg-\frac{v^2}{1325}, \qquad v(0)=v_0 \quad x(0)=x_0[/tex]

[tex]\frac{dv}{dt} + \frac{v^2}{1325m} = -g[/tex]

As far as I can see, the method of integrating factors does not work here. I don't know what to do. It is possible that I made a mistake in the D.E. set up.

Any help is highly appreciated.
