Yes Grity thanks, good way of looking at it. We'll assume up to circa 100g, anywhere form 60 to 100 ++ seems the ball park actually. Certainly fits with some of the post mortem findings .
@Lonewolf and HarryMann
if you stopp a falling pelvis with a vertical speed of 15000 ft/min (15000*0,3/60 =75 m/sec) with a constant force of 100 g-load`s (100g=981m/secē) it stopps to zerro after 75/981= 0,076 sec and a way of less than 3m !
water is nearly incompressible at this speed, (within 0,07 sec it can not move much to the side), it makes not realy a great difference if you crash into concrete or water with 75m/sec !
and this very short stopway is plausible:
ca. 3m will be the sum of the compressible space between the pelvis and the water, (the space under the seat, the airspace into the baggage compartment, and the construction space in the lower fuselage.....)
