I have been given an equation which is first order ODE of the velocity v(t).

v'(t) = g-(k/m)v(t)

Where g is 9.8m/s^2, k is a constant of proportionality based on the size and shape of the body falling, and m is the mass.

I am asked to find the general solution of this DE, satisfying the initial value v(o) = v0(initial velocity).

I believe that I am supposed to take g-(k/m) to be a constant. Any suggestions as to how i should go about solving this?
