Suppose a particle with mass m release from rest in a uniform gravity g. Suppose the drag force is proportional to speed square, Fdrag = bu^2. Assume the geometry, viscosity, and other properties are such that b = mg/c^2. Write down the relativistic equation motion and find an expression that gives the relationship between velocity and time.
