RE: Motorcyclist's life saved by an airbag
ok, so i just sent this arcticle to the super genius physics programmers that work in my studio and this is what i got from them....
"Due to rotation (that is, angular velocity), his local lineary velocity at the point of contact could be almost anything, including being quite large."
"I’m no accident expert, but it is not clear to me how they arrived at the 140 mph number. "Impact rate" is not a technical term I am familiar with. I think they made that up, and the "140" number too, just as you presumably suspected when you asked the original question, they are full of it "
so it looks like maybe some numbers were fabricated....he may have hit the ground with a little more force then 70 mph depending on the trajectory angle, if he was rotating in flight and what angle he hit the ground at, butprobably not at 140

RE: Motorcyclist's life saved by an airbag
i dunno. i still don't get the 140mph... no matter how hard i think about it. if you're following the speed of traffic, and you rear end someone.
isn't terminal velocity for a human being 120mph or so? and doesn't it take about 300 or 400 feet to reach that speed?
i think someone needs to draw me a picture to make me understand that.
sorry, i'll stop being a scientist now.
ejected 100 feet in the air hitting the ground at an impact rate of 140 mph

I could just see myself forgetting to detach the rip cord, and when I go to get off my bike POOF! I'm the damned Michelin man.

There's enough play (about 30-60cm, or 12" - 18") in the coiled cable to allow dismounting with the device still attached, but it's not hard to remember that you're connected to the bike. As soon as I swing a leg off my bike, I can feel the tug of the cable, saying "Hey, remember me?".
The directions indicate that it takes somewhere around 8-12kg (~17-26 lbs.) of force before the airbag will activate, so it's unlikely that it would inflate just by walking away from the bike with the cable still attached.
