who does not speed

[blondini]

The answer is simply 5 mph, which seems insignificant because a car can stop from 5mph in the blink of an eye., i.e. 0.25 seconds at 0.9G deceleration.

But although the faster car only takes an extra quarter of a second extra to stop, it has already travelled further than the slower car during braking.

Under the same scenario as previous question, what speed will the faster car be doing at the point where it has covered the braking distance of the slower car?

Think about it..........(or ask B'staine)

thrush is an irritating fungal infection as well as a bird.

for a female, this would be referred to an irritating c**t.

Napolean and Illya had a lot of run-ins with thrush

Oh ... I see, thanks for the enlightenment ... Yup, that'll be me then

Take your little feet Aspley and shuffle them up REALLY close to the sink ... Less chance of getting lather down your pinny that way.

Assuming, again, linear and identical deceleration, it would be doing 18mph.

I presume that your implication is the observation that, if traveling at 35mph instead of 30mph, a car that would been have capable of stopping just before hitting a child on a pedestrian crossing would instead cream into the child at a potentially lethal speed.

A good illustration of why speeding in a built-up area can be very bad.

Thanks for working that out Softus.

18mph is just over half of 35mph and I think it is quite striking that a car doing 35 will only have lost half its speed over the same distance in which a car doing 30mp will stop.

supposing the other car had ABS and was on a conveyor running in the opposite direction?

Tim, have you ever considered that Santa Claus might be watching this forum?

a.b.s. can prolong stopping distance, though it increases the ability to steer.
