An object weighing 34.518379357 kg, free-falling at 4.2(?) m/s, travels 0.889m, before it begins decelerating when it makes contact directly on the top of a person's head.
Within what I would guess would be perhaps maybe 2(?) milliseconds after deceleration commences, the first intervertebral disc between C-2 and C-3 vertebrae begins loading up.
It's tensile strength is instantly overwhelmed as the impact force of 11986.30338302126 N forces the inner nucleus pulposis outward radially, generating fissure pathways through the 13 concentric rings of lamellae comprising the progressively more fibrous Annulus Fibrosis, until the inner disc material breaches its outer wall, and also breaches the immediately adjacent central posterior ligamentous capsule, creating what is known as a transligamentous disc extrusion pressing into the spinal cord. (Ouch!)
This process repeats as the impact force continues downward until the energy is finally absorbed 9 intervertebral discs later. (ouch x10!)
The estimated cumulative height of the affected intervertebral discs is 24.5 mm.
Treating the 10 discs as though their heights were the same (even though they are not), how would one APPROXIMATELY plot their decelerating velocity and position in milliseconds?
Since I am an absolute beginner in physics, I cannot even begin to throw out an idea of where to start. Can anyone help?
