The second model attempts to account for rotation but it doesn't account for varying angular velocities. Look at the variables, no new variables are included (unless you count the poorly defined constant). Does a coin "flip" that is a simple drop have the same odds as a fastly rotating coin? What if the flip is along the verticle axis instead of a horizontal axis or at angle in between?
