Considering it has had a (half-hour) silencing effect.. perhaps it should get the "most useful" award for use of Physics on Vorb?

Its about as useful as mathematical economic models..

Meh it wouldn't be that far off. Would be easy to factor in the effect of gravity if you used vector diagrams and new the slop of the hill. The really deciding factor is if the bike had got "air" ie the down force on the tires had changed going over the brow as iodi said and would it come back to normal in the reaction time? Being as it was on dry roads I don't think the friction bit would of changed significantly.

what about greater deceleration via increase air resistance from higher velocities?

Far off what? A hypothetical situation that you have concocted on the basis of what you read on the internet? Or reality?

Is that roadie speak for I never get close to the limits of my tires grip anyway. The temperature pays a big part in grip, so does the road surface. Seeing as the road on both sides is a fairy high bank, depending on the orientation of the said piece of road, the road might likey have been mossy on the sides. What if upon seeing the cops car in the middle of the road, the rider reacted within .75 of a second, grabbed on the brakes, grabbed too much brake in the panic situation, locked upm had to get back off the brakes a bit to regain control, and then back on thus making the available braking distance much much less. Without knowing any of these factors, and other onsite factors, posting up formulae and postuering that he had to of been doing this or that shows you up for a smuck

Meh all I was out to prove to HDC that there is a huge difference between a rider travelling at 100 and 150 kph. Flame me all you want end of the day it is going to change much.

whats the difference between an economist and the man in the street?
the man in the street realises that he knows shit about predicting the economy

You only have to need to have watched a TV ad break twice in the last 10 years to know that.
