Hi Im trying to simulate a car crash scenario mathematically and come up with reasonable numbers for a project. The problem is I do the calculations and everything seems mathematically correct but the numbers seem weird. I simulated an 80 kg passanger in a car crash that was going 20 m/s and the car has crumple zones of .5 m, the seatbelts streatch 20 cm, and the airbag+seatbelt area on the driver is .2 m^2 After doing the calculations I got numbers which seem high but I dont know, considering this is a pretty fast crash here. I got pressure on the driver of 114285 pascals, with an acceleration of about 300 m/s. Area these numbers ridiculously high and I did something wrong, or do they seem about right considering the scenario?
