Here's my back-of-napkin calculation.
1/2 mv^2 = F * d
Mass = 0.0032kg
Velocity = 88 m/s
d = 0.008636 (half the diameter of a paintball; will explain later)
Average force = 1434 Newtons. This is obviously an average force.
Assuming average head is about 8 lbs (3.63kg):
F = m * a
1434 = 3.63 * a
a = 395 m/s^2
g = 9.8 m/s^2
a = 40.3g
Alone, not enough to meet the 70g threshold for concussion that's thrown around, but high enough to consider, especially given how many variables might be involved.
More on this later.
