Re: M1 May 2012 Edexcel - Post Exam thread - Paper and Solutions in the FIRST POSTI thought it was OK. I lost either 2 or 3 marks (out of 4) on the sinking into the ground question, because I took the force going down as mv instead of mg for some strange reason. I also think I lost 0-3 marks on the 3 marker at the end of the paper because I drew thrust in the wrong direction (but got the correct answer, as a negative, where I simply changed the values on the left of my equations to be negative also so that it fitted).
I'm thinking 69/75 assuming I've made no other stupid mistakes I haven't foreseen yet.
The exam solutions would be just swell right now to put my mind at ease. -

Re: M1 May 2012 Edexcel - Post Exam thread - Paper and Solutions in the FIRST POST1) V = 1.5MS^-1, M = 0.3KG
T = 115 for that A to B thing
0.316m for that ball sinking into the ground question.
5km for the vectors question, then something like 12.625 for the due north bit.
Thrust = a = 1.25, then tension in string = 1.375, then speed at t = 6 = 7.5, distance travalled = 7.5, thrust = 1/8
Can't remember any more! -

Re: M1 May 2012 Edexcel - Post Exam thread - Paper and Solutions in the FIRST POSTuh uh. 302 I seem to remember getting. There was a strange sense of deja vu doing that one I think there was an incredibly similar question in a past paper I did...(Original post by Gman1234)

Re: M1 May 2012 Edexcel - Post Exam thread - Paper and Solutions in the FIRST POSTYES(Original post by theseeker)
Does anyone know that if you show 2 methods or more, the best one counts apparently? Right?
That was the one I thought I'd screwed up...
