Back to basics- Laws of Motion needed for headway calcs

[Peter]

Hmmm, on the basis that there are not any offers for correct solutions to the examples, can I assume that either a) you are all far more clever that we gave credit for; b) you are all far less clever than we feared; or c) the offer of smug points alone is not enough incentive to get you to go pulic with your ideas. Perhaps if I up the stakes to a mars bar?

If you are stuggling with this sort of calculation, please let us know so we can offer some more information to help with specific areas.
