Question 1)

If a ball of mass 2kg and velocity 3 m/s collides into a stationary ball of mass 3kg, with e=2/3, then the 2nd ball proceeds to hit a wall with e=2/5 then continues to collide again with the 1st ball, which then proceeds travel off the end of a 2m tall surface, at what point will i give up on revision and decide there are better things to do with a day off school?

Yes it's that time of year again (although each year there are two of these times, so it's one of those times of year again technically), Christmas has come and gone, the New Year has rolled in and *BANG* exam time. With barely enough time to get settled back into school mode, and remember all that stuff that has been inevitably been forgotten over the festive period, you're expected not only to recall it at will but fully understand exactly how it all works. However during any other time at school that would seem like a simple task to perform, however as soon as revision starts everything seems so much more complicated and basically the whole course has to be relearned over again.

So to answer the question posed at the start, about an hour the answer seems to come out as. So far all i've managed to handle is one past paper before the distractions kicked in, and as you may have guessed currently that distraction would be this post. However the other big distraction at the moment is the constant refreshing of the cipher challenge's webpage, as today is the day that they release the final results, which could potentially make me a bit richer by the end of the day. As well as that my James Bond boxset has been sat by the TV now for over two weeks and i've only managed to watch Dr.No, but luckily so far i've managed to escape that temptation, meaning if i keep it up for the rest of the day, i might get another past paper done.

This would mean that in total, having had a whole day off, i will have managed about 2 hours of revision, and the annoying fact is that this module is the one i find most fun (can i use the word "fun" in this situation? not sure), and so i can't begin to imagine how much i'll manage on the other 4 exams i have to do, which could end very badly as there the ones which are going to require more (and definitely more boring) revision. Which will perhaps explain why for June, instead of learning S3 with the class, instead i shall be self-teaching the much more logical (and thereby more exciting) M3.

Well i'll keep it short, as i'd better get that 2nd paper done, where hopefully it'll all make sense otherwise there could be some very frantic and last minute look over notes/textbook/google for help on understanding what on earth the question is on about, and realising that infact after relearning it all, i still haven't got a clue what's going on.
