You're kidding right? You lose around 4 meters to air resistance fireing 45 degrees from 0 -> 0 at 12 m/s. This is fairly nontrivial. Initial deceleration is easy to calculate
F= 1/2 Cd * rho * A * v^2
for a poof ball, thats's about
F= 7.52e-3 * v^2
F= 1.08 Newtons.. that may seem insignificant.. but the poof ball is light..
F=ma=1.08 , so taking m = .18 kg we get a = 6.016 m/s^2 deceleration..
yes, that's about 2/3rds g, that's nontrivial.
