Hey guys, I'm going to say right up front that I haven't a clue how to do these calculations, but I have a scenario that I would like the math to if anyone can help me figure it out. What I had been able to attempt to figure out doesn't seem tangible? The formulas I had researched/used was KE=0.5mv^2 and F= mass* acceleration/time* proportionality constant. In the scenario I will supply both the US customary system and the metric system so you can choose what set of numbers you'd prefer to work with. I am willing to do my own math as well, so if you could tell me which formulas I need, I can go from there!

Here goes:

Imagine that there is a 3 car accident. A compact car (2,425.1 lbs./1,100 kg) is making a left turn at 35 mph/56.327 km per hour. The car is hit on its side, just behind the passenger door, by a midsize car (3,154 lbs./1,430.63 kg) traveling at 44 mph/70.81 km per hour. Then a midsize SUV (4,094 lbs./1,857.01 kg) barrels through going 57 mph/91.73 km per hour. A rough estimate of impact damage to each vehicle is as follows: Compact Car (5ft./1.524m), Midsize Car (Front-4ft./1.2192m, Back-6ft./1.8288m), and the Midsize SUV (6ft./1.8288m).

Now here's my question(s); 1) How much force (force of impact) would be applied to the compact car from the overall collision, and 2) Would that impact send the compact car into a rollover, and if so how far would it travel?

If any other information is needed, let me know and I'll do my best to supply that. I know there are a lot of factors that can go into a car accident of this caliber, but I only need a generalization. This is a topic I had always been curious about. Thanks in advance you guys!

I'm sorry but we don't allow traffic accident analysis here. Accidents are far too complex to reliably analyze. Please contact a specialist if you are in need of an analysis.
