ok so i have a question i'm really hoping someone can help me with. i got in a car accident recently and i want to prove that the person who hit me was speeding but i'm not sure how to do it. i am actually an engineer so i really should be able to do this on my own but i'm a civil engineer and so i haven't taken a physics course for a long time or applied any physics for a long time. anyway, here's the deal. i was pretty much perpendicular to the impact so i got hit in the side of my car right above my back tire. so i was going to use the front tires as the pivot point. i did almost a complete 360 (let's say i did about a 300 degree rotation) and the speed limit was 35 mph on that road. judging from the impact, the damage to my car, the fact that i almost did a 360 and seeing how fast he was going, i am positive he was speeding. but can i prove it mathematically? also i gathered some data such as car weights and wheelbase lengths, etc. so i have that info. my car outweighed his by almost 1,000 lbs. again, further proof that he was speeding i think.
