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