Two algorithms, GRAS and IMPAC, used to calculate crash delta-V and impact velocity are compared. Each is observed to have common features but important differences.Error sources from restitution and intervehicle friction are discussed. Comparisons of accuracy in reconstructing delta-V are discussed but found inadequate for objective comparison.
