Query: From E=mc^2 to the Lorentz transformations via the law of addition of
  relativistic velocities   In this paper we show how to get the Lorentz transformations from E=mc^2, the
laws of conservation of energy and momentum, and the special relativity
principle. To this end we first deduce the law of addition of relativistic
velocities
