So how did it go people??? i thought that it was another nightmare... the questions are just so time consuming... and it tends to get kind of tricky.... maybe it's just me...

Is someone willing to type out the answer for M2? Hope Dan... sees this message...

i answered all of the questions although i have no clue if i was right or not on many of them. What did you get for the projectile question, i got u as 7 and theta as 68 degrees. How about the penultimate question for part a i got work done as 324 watts, part b, 10.6m/s and the acceleration as 0.81. The statics question i did not really have a clue about although i did try it. Could anyone scan a paper? Thanks.

i thought it went ok.... there was that question about the reaction on the hinge worth 6 marks. I got 784 N but did that in 2 lines, so how can it be 6 marks??!?! i couldn't see any other forces acting on the girder, and when i came out of the exam, everyone also got 784 N. Either everyone is wrong or Edexcel gave 6 marks that should have been worth 1 mark!!!

Yeah I got the R=784N in only 1 line, sat there for ages trying to find a more difficult method!! I got 19/15 for the mass one too, trying to remember any of the other answers....I got 9.33ms-1 for the girl going down hill, and 0.501ish for the acceleration. For the coefficent of restitution ones I got speeds of 1/3u(1+e) and something like 1/2u(1-2e) (not sure about the half bit tho) and i got 0<e<.5

If I remember any more I'll post them

I got 1/2< e < 2/3 after staring at it for a while.

About the 6 mark question. It said find the magnitude of the force, so I'm guessing it had horiz and vert components. I resolved each way and got a different answer (something like 877N). That's the only way you could make it a 6-mark question.

The reaction had two components one of them is 784 (the horizontal one) the other one was some 324 or some thinbg. u have to add the squares of both and root it to get the magnitude of reaction

Yes! That's what I did! I thought it was too easy to do it in two lines.

i got 224 watts and the accn was .59ms^-2

the two velocities are 1/3u(1+e) and something1/3u (1 +2e) (not sure about the 1/3u). the first Q was 9 - 2root 3?

It was quite hard the paper. You think it was as hard as P3?

I thought the exams was very easy, the first time Edexcel have managed to pitch their exam at the right level.

" i answered all of the questions although i have no clue if i was right or not on many of them. What did you get for the projectile question, i got u as 7 and theta as 68 degrees."

u only had to work out tan theta and not theta itself.

i got centre of mass as 1.3a and m = 2M/15

the best thing about this exams was the time - there was lots of it! i finished the bulk in bout 45 mins then went back checking over everything

I was pretty good at M2 getting 90's and 80's% in past and practice papers, but i found this exam really hard, i think iv got a C maybe D i feel really down cuz of this.
Has anyone got the complete answers for this test?
