Discussion Overview

The discussion revolves around estimating the speed of a vehicle involved in a rear-end collision. The scenario includes details about the weights of the vehicles, the distances traveled post-impact, and the conditions of the accident. The focus is on applying physics to understand the dynamics of the collision.

Discussion Character

  • Debate/contested, Technical explanation

Main Points Raised

  • One participant describes the circumstances of the accident, including vehicle weights and distances traveled after impact.
  • Another participant notes that accident reconstruction is typically a task for trained professionals, suggesting that simple online discussions may not yield useful results.
  • A participant expresses curiosity about the mathematical equations that could be used to estimate the speed, indicating a desire for a more analytical approach.
  • One participant questions the logic of the distances traveled by the vehicles, pointing out a potential inconsistency in the scenario described.
  • A later reply reiterates the complexity of traffic accident analysis and advises seeking professional help, emphasizing the limitations of online discussions for such inquiries.

Areas of Agreement / Disagreement

Participants generally agree that estimating speed in this context is complex and that professional analysis is preferable. However, there are differing views on the feasibility of using mathematical equations for such estimations in an informal setting.

Contextual Notes

The discussion highlights limitations related to the lack of physical investigation of the accident scene and the challenges of applying theoretical physics to real-world accident scenarios without comprehensive data.

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.
