and when all that momentum has a small point as the frontal area....

kinetic energy = half x mass x velocity squared
= 0.5 x 300 x (27.8 x 27.8)
= 116 KJ
or roughly the same force as 1000kg dropped on you from 11m above...
Seems kinda large, so anyone who's a little better at physics is welcome to prove me right/wong.

That's the one hazard02, but remember that velocity is relative when discussing two vehicles. If the vehicle is travelling along any vector that is toward you the energy value involved in the collision goes up.

See the Motorcycle?

A picture is worth a thousand words.

The Honda rider was traveling at such a "very high speed", his reaction time was not sufficient enough to avoid this accident. Swedish Police estimate a speed of ~250 KM/h (155mph) before the bike hit the slow moving car side-on at an intersection. At that speed, they predicted that the rider's reaction time (once the vehicle came into view) wasn't sufficient enough for him to even apply the brakes. The car had two passengers and the bike rider was found INSIDE the car with them. The Volkswagen actually flipped over from the force of impact and landed 10 feet from where the collision took place.

All three involved (two in car and rider) were killed instantly. This graphic demonstration was placed at the Stockholm Motorcycle Fair by the Swedish Police and Road Safety Department. The sign above the display also noted that the rider had only recently obtained his license.

At 250 KM (155 mph) the operator is traveling at 227 feet per second. With normal reaction time to SEE-DECIDE-REACT of 1.6 seconds the above operator would have traveled over 363 feet (21 yards more than the length of a football field) while making a decision on what actions to take. In this incident the Swedish police indicate that no actions were taken.

Nope don't see it, but it has been posted so many times before I don't think ayone will care

**onearmedbandit** · 23rd March 2006, 16:42

Hard one to search for I suppose (using the site search engine) but yeah it is a major repost.

**imdying** · 23rd March 2006, 16:48

*hides and runs from the obligatory repost pictures*

**froggyfrenchman** · 23rd March 2006, 16:50

cant see any pics...

Consider yourself lucky.

The RC45 has a nasty scratch. Not the sort of thing you want to do to an RC45. Those fairings are expensive.

It's pretty tough to look at. I am in tears.

There are only like.. 1100.. of those things..

No suprise at $50000 each. Doesn't the guy at Ashburton have two in the shop? And what happened to that one that was stolen and painted black a few years back? I know they recovered it, wasn't it recovered with that painting that was also flogged? (yeah, vague I know)

**Motu** · 23rd March 2006, 17:39

I can't see the picture - I've seen it so many times I think my brain no longer registers it....

**martin** · 23rd March 2006, 20:34

sorry guys i must try harder next time

Don't know if this has done the rounds already so I take no blame!

But OUCH!
