There is no such thing as "explicit 3-D information to the brain." All our brains get are what our sensors perceive. What people call 3-D is really stereoscopic display (and the associate perception process is stereopsis) and it is just one cue to depth (the third dimension). Others are accommodation, occlusion, perspective and colour saturation. With moving objects there is no doubt a complex interaction of these effects and the presumed kinematics of the object. Stereopsis is not even the most important. At anything past middle distance, stereopsis is of diminishing importance (because the images received by the two eyes don't differ enough. When you see floating mountains in "Avatar" with a pronounced stereoscopic effect, they have been rendered with an exaggerated eye separation (or alternatively as if you were looking at a micro-world close up).
Two cues which are not implemented either with mono or stereoscopic displays are accommodation (where the eye must focus differently according to depth) and parallax (where if you move your head, things in the foreground should move relative to things in the background. Inconsistencies in these cues are presumed to be what gives you headaches as your brain tries to resolve the discrepancies.
Unfortunately, that is not good enough if you use it for multiple sites/systems. Site A knows the answers to your questions. They may also be able to guess or discover other sites you use. Unless you trust everyone at Site A, what it to stop someone from there using your answers to get to your account on Site B?
Unfortunately you need to tell a different lie to every site, and that is hard to remember!
Actually it the the momentum which is roughly equal (the difference going into the gas). Most of the energy goes into the bullet. The smaller the ratio of the bullet mass to the gun+shooter mass, the higher the proportion of the energy that goes into the bullet.
The bullet may decelerate much more quickly than it accelerates though, resulting in the bullet applying a much higher peak force to the shirt than the peak force of the gun's recoil.

There is opensource software available: http://elettrolinux.com/Analyze-Visualize/hantekdso-support-to-dso-2150.html. I use HantekDSO. I found a few bugs which I fixed and reported (no idea if they have been adopted).
