After rewatching episode 1 it became apparent that Ruby shot herself up the building at a ridiculous velocity. She went up the ~20M building and a bit over ~2-3m (I am just going to say 25m total) in 0.45 seconds. Using this information the average air resistance + gravity can be calculated. a=-(2x/t^2)+2v/t Where a is acceleration(m/s/s), x is displacement(m), t is time(s), v is final velocity.(m/s) Substitution a=-((2*25)/0.45^2)+(2*0)/0.45^2 Gives a=-58.66m/s/s This is far more than the -9.81m/s/s (earth’s gravity) used before but it also includes air resistance. Once again doing the calculation to find initial velocity as before: u^2=v^2-2ax Where u is initial velocity(m/s), v is final velocity(m/s), a is acceleration(m/s/s), and x is displacement(m). Substitution u^2=0^2-2*-58.66m*25 Giving U=54.13m/s This compared to a .50BMGcal recoil (5.73m/s) is 9.45 times larger. But seeing that this is one of Ruby’s more powerful shots it, would seem that the dust and her aura would need to be able to give a ~10x increase in recoil.
