I was in a car accident Friday night and we both claim the other guy ran the red light. I drive a 2005 Audi A4 which is approx. 3205 lbs, I weigh 350. the other guy was in a 96 toyota corolla which weighs 2,553. I was going about 4 mph when the accident occurred, I had been sitting at a red light it finally turned green I started going. The other guy I estimate was going beteen 35(speed limit) to 45 I think he was speeding to catch the yellow light but was way to late. My front Bumper is barely scuffed his car was scraped down the right side and it tore my front license plate off completely. If I was the one who was speeding I am estimating I would have been going roughly 35 mph myself which if he was going 35-45mph I believe he would have been in the medium which was immediately next to his car. I hit him in the drivers side door. If there is any more information I can provide. I love everything to do with physics especially the cosmology side of things unfortunately numbers confuse me a great deal and my school did not offer physics. Any help would be appreciated and would gladly return the help of any computer related questions, I am an IT guy.
