A body falling in a relatively dense fluid, oil for example, is
acted on by three forces (see Figure 2.3.5): a resistive force R, a
buoyant force B, and its weight w due to gravity. The buoyant force
is equal to the weight of the fluid displaced by the object. For a
slowly moving spherical body of radius a, the resistive force is
given by Stokes's law, R = 6*pi*u*a*|v|, where v is the velocity of
the body, and u...
