    That is very true. As I was doing that question I had a feeling that the "find the range of P" question will catch people out.

    Yeah... There was also a similar question on this year's M3 paper.

    C'est la vie.

    Was this year's paper easier than last year's?

    BALLS cos i drew the diagram wrong i got impulse to be at 60 degrees and it allwent wrong from there
    so 6 marks for me lost.

    More like 1 or 2 marks.

    Wasn't it 1/9<f<1?

    I got that, but then I thought it was wrong so I crossed it out and did another STUPID method and got better numbers thinking I was right. Ugh.

    Overall I found the paper to be quite reasonable. There was a fair mix of questions with no one problem/topic/field containing disproportionately high marks (Although something could be said about the mark allocation for Q7 - 17/75, 23%).

    The only question that could have let me down was Q6. I've never been a big fan of ladder-based problems, and thanked god when I saw it was a standard labber problem and not tension based, but was stumped on Q6 part b). I managed to decipher that P >= 0.4mg, but couldn't figure out what level of force exerted would unbalance it, so I only gleaned minimum marks for that part.

    I had a period of complete shame when I couldn't manage to work out how long that ski jumper was in the air for, as I was taking a positive value for g ! Luckily, I JUST managed to finish that question in time. And for the Impulse angle question, I've attached/embedded what I did for that question as an image.

    it was 0<f<1/9 but instead i put -1/9<f<1/9 but in 2 separate equations so it mite go unnoticed

    The reason I didn't put 1/9 down because one time I found it to be negative.

    I take it that was the restitution question? I thought that a high restitution coeffecient resulted in more rebound. So if it was zero, it would hit the wall and just stay there. I may be wrong on this, anyone who can be certain please intervene...

    For the KE lost question, what did you guys get?

    I remember I got either 40, 60 or 80 (or something like that).

    Yes, I'm pretty sure that's what I ended up with. And for the KE lost question, I think I got 40J. Think.

    0.4mg < P < 13.6mg

    The angle for the impulse question was somewhere around 60-80, and the angle for the CM question was somewhere between 15-25. I don't really remember.
    YAY - that exam was the easiest M2 I have ever seen.

    It certainly wasn't difficult. There wasn't the usual drones from people as we poured out of the exam room.

    Yeah, same here - It is a result of terrible teaching in my school though as well as the A2 class being timetabled together with an AS class in the same room with the same teacher - We only get half the teaching we should so you can expect the majority of people to get terrible grades.

    My college, which I shall not (Maybe later) name has some outstanding members of staff and is relatively well organised. However, there is quite a few "bad eggs" when it comes to lecturers which bring the side down. As a sidenote statistic, my college is ranked between 1400 and 1500 out of 2787 (According to the BBC) per A/AS-Level results, which just drops it into the lower half of the educational spectrum. However, all my educational woes stem from attending an absolutely diabolical secondary school (28% 5 A* - C's). On occassion, the school janitor would monitor our English lessons, no teacher - just books, but the JANITOR in the room.
