I am not too good at physics so I thought I would post here to find an answer to a question. I was recently involved in an automobile accident and was wondering if there was a formula to calculate how fast the other car was traveling at the time of impact. The details are as follows: Vehicle 1 (v1)was traveling left and vehicle 2 (v2) hit the right front, so v1 was traveling at 0 mph in the direction of being pushed by v2 (think of an L or a T) Vehicle hit (v1): 3600 lbs. Vehicle doing the hitting (v2): 2600 lbs. Distance v1 moved after impact: ~ 2 meters Time: ~ 1 second Speed after impact: 0 mph Thanks if you can help out. Edit: Equation 2 on this page http://www.accidentexpert.com/engr/skidart1-a.html [Broken] is what I am after I think, but I need to find out what Ve^2 is ... is there any way of finding this out? This would be the speed at impact.
