Homework Help: Calculating the force during a collision.

  1. May 26, 2012 #1
    1. The problem statement, all variables and given/known data

    Okay, there was a side on collision between a car and a 4WD, the 4WD crashed into the side of the car. The accleration experienced by each driver has been given: Car:114.9 m/s2, 4WD : 43.9 m/s2. The masses have been give: Driver of Car: 105kg, Driver of 4WD: 60 kg.

    The thing that confuses me is that the distances that the vehicles crumpled has also been given, it is stated that it is relevant, but i cant see how: Car side: 54cm. 4WD bonnet: 1.12m.

    Do i just use the F = ma to find the force during collision, or do i need to use the distances.

    By the way the reason i need this is to draw a Force vs. distace graph, so the distance might be relevant.

    2. Relevant equations

    3. The attempt at a solution

    If this were a real problem then how the vehicles crushed would be very important. You would use that to estimate the accelerations. But since the accelerations are given, then you can use the F=ma to find forces on the drivers.
