Hi, I'm a person that likes physics a lot, but I'm unsure of how to address this problem I'm currently facing. I was recently in a car wreck, and am backing myself up with evidence to go to court with. A woman hit me in the back right side of my car, and I'm not sure how to calculate the force of her car that was transferred to mine. Okay. So I'll give you the givens, I suppose. In this situation, I am A, the woman is B. Okay, so the explanation is somewhat difficult. The woman stopped at a stop sign, and then accelerated her car to go across an intersection, and into a parking lot. I was driving 25 mph through that parking lot, in a perpendicular direction to where she was going. The distance she travelled before she hit my car was about 50 feet. My car spun a full 90 degrees. I'm not sure how to calculate the distance of that, my car is about 14 ft long though. Her car weighs 1888kg, plus two 60 kg passengers. 2008 kg total. My car weighs 1094kg, plus one 60 kg passenger. 1154 kg total. I'm honestly not sure about how fast she was going when she hit me, but the frame damage suggests over 20 mph. Lets say 25 mph. I'm a bit rusty on my physics, but wouldn't that be about 25100N of force, with an average acceleration of 18.3 fps? If I'm wrong, please correct me.
