B Speed vehicle travelling on impact

  1. Feb 20, 2017 #1
    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 travelled 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.

    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.
