    Linear vs quadratic drag limiting displacement

    Why does a surface with resistive force mkv^2 have displacement given by x = 1/k(ln(1+ukt)), hence divering, whereas a surface with resistive force mkv has displacement x = u/k((1-e^-kt)), and converges to x = u/k. Is this because the quadratic drag model is incorrect?
