Discussion Overview

The discussion revolves around calculating the impact speed of a vehicle involved in a collision scenario, focusing on the specifics of the vehicles' weights, angles of impact, and resulting motion. The context is primarily conceptual and mathematical, as participants explore the physics involved in vehicle dynamics during a collision.

Discussion Character

  • Mathematical reasoning, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant requests assistance in determining the impact speed of vehicle B after it collides with vehicle A, providing detailed specifications of both vehicles and the circumstances of the collision.
  • Another participant expresses skepticism about the appropriateness of the forum for accident investigation-related queries, suggesting that professional help may be necessary for such matters.
  • A participant reiterates their need for help, emphasizing that their question is not related to accident investigation but rather a scientific inquiry, and requests assistance with their calculations.
  • Details provided include the weights of both vehicles, the angle at which vehicle A is turning, and the distance vehicle A travels post-impact, which are critical for calculating the impact speed.
  • There is a request for the original poster to share their calculations and the varying answers they have obtained, indicating a collaborative approach to resolving the inquiry.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus on the appropriateness of the forum for this type of question, and there is no agreement on the calculations or methods to determine the impact speed, as the original poster has reported differing results in their attempts.

Contextual Notes

The discussion lacks specific assumptions or mathematical steps that the original poster has used in their calculations, which may contribute to the differing answers they have encountered.

Welcome to the PF.

We don't try to participate in accident investigations, if that's where you're headed with this. You need to hire a professional for such things. :smile:
 
it is not for accident investigation it is a question i have to solve but come up with very different answers. I am sure if it was regarding accidents i would take it more seriously than a science forum. any help appreciated :)

Then sure, fire away... :smile:
 
vehicle A weighs 3677lbs (1667.86 kg) with passengers and fuel. vehicle B weighs 3475lbs (1576.23 kg) with passengers and fuel. vehicle A is turning left at an approximate 70 degree angle. Vehicle B hits vehicle A centre passenger side sending vehicle A into a 160 degree clockwise rotational spin ending up 12 meters away from point of impact. Vehicle B has not moved since impact. how fast was vehicle B travelling?
 
this was on asphalt i might add...

You said you keep coming up with different answers. Can you show us your calculations, and the answers you are getting? :smile:
