[Phys-l] Impact velocity



Article on first real test of a motorcycle airbag.

http://www.wbaltv.com/news/14328936/detail.html

My question is what is an "impact rate"? How is it different than the speed one hits the ground at? It would seem that 140 mph was excessive - perhaps not survivable. Is some strange unit or just media nonsense. No mention of charges against the cyclist.
