sorry not sure i got what you say
2 cars hit each other at the speed of 30 each one of them.its like one car hits the wall at 15??
isnt it like a car hit a wall at 60?
so the question is this.
2 cars with the same mass hits each other at the speed of 30 miles.
at which speed a car needs to hit a wall in order to get set same impect?
i don't care what Will hurt the driver more.
thanks!
