He falls for approximately 6.1 seconds...
His downward speed at impact is appoximately 134 mile/hour.
His horizontal travel beyond the edge of the cliff would have been ~44 feet; within the first .4 secs the vehicle would have turned nose down and its initial rate of speed would have increased from ~61 fps to roughly 188 fps at impact; time of fall would be ~6.1 secs as previously said.
Ok, smarty pants. Assuming the front wheels starting falling before the rear, what was the rotation rate about the pitch axis and what was his pitch angle at impact?
