where p ¼ m_ z is the momentum of the liquid in the straw, q
is the density of the liquid, h is the depth of the bottom of the
straw below the bath surface, A ¼ pr2 is the cross-sectional
area of the straw, and b0 is a phenomenological damping
coefficient. An important difference with most introductory
physics problems is that the mass of liquid in the tube is
changing as the liquid level changes in time. Thus, we can
write down the mass of the liquid in the straw as
