Re: desperate for answers

this picture seems to show where the area of contact was and so begs question: which vehicle had this lane as the proper lane of travel? Was your daughter headed towards the camera position or the other way? What is the make/model/year of the two vehicles (I may do some exploratory simulation demons...

Folks weren't responding to this so after 3 days...sorry to be posting so much... Answer is YES...however...it depends... On the logic/trigger for the recording of lateral acceleration since when it starts and ends may affect what total lateral DeltaV is calculated. For full scale testing and simula...

Re: Determining fault in a complicated case.

Hey Rusty, Interesting points and sorry to blah blah blah more but since neither of us is involved in that case this is FUN! Obviously most important step is determining speed of vehicles at contact and where was the location of each vehicle AT CONTACT. then back things up. Second most important ste...

Re: Delta V question

you say 'post impact speed was calculated' check your assumptions since drag factor? amount of rotation? terrain up or down?
and on question of adding deltaV and post impact speed...see Beginners Error#1 in Reconstruction 101 includes a similar type question of how to combine speeds
