I suspect the maths is all wrong but, jsut out of curiosity:
Seat belt
No seat belt
Car speed
80mph
Your weight
150lb
******************************
Crash
Average impact force
244,542lbf
Stopping time
2.24ms
Deceleration
1,630.3g
It feels like being pressed with a mass of
244,458lb
“I suspect the maths is all wrong but, jsut out of curiosity:”
Terms are wrong. lb ft is a unit of work not force.
Lb is a unit of force. (Typically not used for mass unless stated). In your use of being “pressed”, it is a force. Mass is not force, only a component of force. F=MxA
Didn’t check your math. But yes, a crushing blow to say the least. My guess is the ground was soft and her true vertical speed is unknown.
