Legendary Dale Earnhardt's death caused NASCAR to make changes to rules
that dictate how to decelerate the body and in his case...the head
His impact was NOT very hard, nor going very fast...
It can be built like a tank and the vehicle survive, but occupants might not
Again, key is the rate of deceleration, or rate of change, for the person (all parts)
Just noodle any of the Sci-Fi movies where they jump to light speed in a flash...
Unless they have some mechanism to keep everyone inside the vessel from flying
to the back of the vessel to become ink spots 'back there'...won't work.
No difference between that analogy and a crash...just different directions of
'the rate of change' in speed
The rate of change for the body and most importantly the head...the brain from
smacking the inside of the skull, is the key to managing a crash
Suspend a bowling ball and soccer ball on a length of rope anchored on the same
eye bolt in the ceiling
The length of rope is sized to have both balls meet in their equator
Lift both up the same angle away from vertical to be horizontal
Let go of both at the same time
When they meet/crash into each other at the bottom of their swing arc...which
on will bounce farther away from the impact at vertical?
The one with less mass, therefore less kinetic energy will bounce farther away
from the contact point.
