    Impact Speed Vehicle

SUMMARY

The discussion centers on estimating the speed of a vehicle involved in a rear-end collision. The stationary vehicle, weighing approximately 1470 kg, was struck by another vehicle weighing around 2000 kg, which did not apply brakes and traveled 36 meters post-impact. The stationary vehicle traveled approximately 24 meters during the same time. Participants emphasize that accurate accident reconstruction requires professional expertise, as the complexities of such incidents cannot be resolved through simple online discussions.

PREREQUISITES
  • Understanding of basic physics principles related to motion and impact.
  • Familiarity with vehicle dynamics and weight considerations.
  • Knowledge of accident reconstruction methodologies.
  • Awareness of legal implications surrounding traffic accidents.
NEXT STEPS
  • Research professional accident reconstruction techniques and tools.
  • Learn about the physics of collisions, including momentum and energy transfer.
  • Explore case studies on rear-end collisions and their analysis.
  • Investigate the role of skid marks and vehicle movement in accident analysis.
USEFUL FOR

This discussion is beneficial for accident reconstruction professionals, insurance adjusters, legal experts in traffic law, and individuals seeking to understand the complexities of vehicle collisions.

Hi guys
hoping someone is able to answer this albeit a estimated reply.
I am trying to figure out the speed I was hit at in a recent accident.

I was stationary at a junction (vehicle weight aproz 1470kg) foot on brake
was hit from behind (vehicle weight aprox 2000kg)
was hit full on driver did not apply brakes (no skid marks) Driver claims not to have seen me

From the point of impact my vehicle traveled aprox 24 metres my foot was still on the brake during this time.

From the point of impact the vehicle hitting me continued to travel 36 metres

It was a clear dry afternoon.

Any help would be appreciated as to an estimated speed that I was hit at.

Thanks

We get similar questions often on PF. But accident reconstruction is something for trained professionals, not amateurs, or even physicists.

A simple question and answer on an Internet forum is not very useful.
 
I figured there must be a mathematical equation to work this out..I guess it's not that simple then ? Thankyou for taking the time to reply Anorlunda.
 
If you were hit from behind, how is it that the vehicle that hit you traveled twelve meters more than you?
 
I'm sorry but we don't allow traffic accident analysis here at PF. Accidents are too complex to give an accurate analysis, especially without physically investigating the scene. If you need help, please consult a professional trained in this area.
