By calculating an approximate maximum distance that shrapnel, specifically a stainless steel ball bearing, would travel after detonation of a high explosive suicide vest IED bombing, I am able to assist a post-blast investigator in thoroughly evaluating all evidence at a scene. The detonation velocity was determined using the Gurney Acceleration of Metal, adapting the explosive mass to be determined based on the density and thickness of the explosive material. The displacement was then calculated using a two-dimensional projectile motion equation including drag, otherwise known as Stokes Law. The maximum values were approximated to be around 80 meters in displacement.
