When Ruby is propelled up the 5 story building we can determine the velocity needed to propel her that high and compare it to a normal .50BMGcal and see how much of an enhancement dust would need to provide.

U^2=V^2-2ax

Where U is initial velocity, V is final velocity, a is acceleration, and x is distance.

V is 0m/s as Ruby lands on the building thus no longer moving.

a is -9.81m/s/s due to gravity.

x is 20 as estimated before.

This then gives

U^2=0^2-2(-9.81*20)

thus U= 19.81m/s

compared to the.50cal (5.73m/s) The difference is about 3.45 times would seem feasible for a magical powder of awesome.
