Empirical observation exercises on interstellar navigation, and finding c using electrons, have been added. There are also new working draft e-prints on the proper-force 3-vector [1] and use of proper: time, velocity & acceleration in an integrative way [2] to make anyspeed dynamics accessible to introductory physics students.
