Well run through a few scenarios (more information on how I made the calculations is shown as a footnote). It seems more practical to jump up at 30 mph (partial impact cancellation) which can effectively cut down the 'g' forces by distributing the braking distance, sort of like the last second "braking" rockets of cosmonaut space craft that fire just before a parachute landing. We tried to give the answer that seemed most likely to minimize the acceleration of the brain and other vital organs, which are themselves soft tissue.
