Don't stress too much. I looked at last years Pre-Release, the questions were really sticking to the material, a lot of them you could answer using the booklet and some required own knowledge. Just work a bit around the topics (look at all the forces for P4 etc..) and just do the questions and you'll be fine. You can post the questions, can't promise I'll be able to answer them all!

Calculate the maximum speed of the rocket.
(This is based upon the rocket travelling the fastest in between 5 and 10 seconds, I'm not sure if this is correct).
Speed = \frac {distance}{time}

Speed = \frac {500}{5}

Speed = 500 M/s

- I think this one is wrong by the way, you've just used the wrong numbers. Distance is 1500, Speed is 5. So 1500/5 = 250m/s

Since these are my answers, some of them could be wrong!
Please tell me if you disagree with something!

Good luck with the exam!!

Hmmm - I don't get what the second half of the journey would be. Why would it be 39 seconds?

I just guessed that as a rough estimate.

If the parachute didn't open, there'd be very little resistance on the rocket compared to when it went up, so the time coming down would be quicker than how long it took for it to go up.

I think that as long as the answer was less than the time it took for the rocket to reach the top of its flight, you'd get the mark for this question. (Within reason, you obviously wouldn't say 0 seconds. :P)
