p=mv, momentum=mass*velocity Let's say a bullet-proof vest travels at bullet-speed toward a corresponding projectile. A) The acceleration to that speed would likely tear the vest apart. B) Assuming slow enough acceleration, the kinetic energy of the vest would be much greater than the kinetic energy of the bullet (if it were traveling at that speed) and thus much greater damage would ensue. It's all physics 1, dude, conservation of mass, momentum, energy, etc.
