Hi all, I always seem to struggle when there is a block going down a slope involving friction and things like that (Almost all Q7s.) Any tips? Also, has anyone done Jan 2010 Q7. ii.b? really struggling and would appreciate a worked solution or some help. Thanks a lot.

The 2009 papers have the highest grade boundaries

Surely lower grade boundaries = harder papers? I found a couple based on this, luckily someone had been through and compiled all the M1 boundaries onto one document, thanks :smile:

Yes but I normally lose marks on silly mistakes rather than not being able to do it so I try the ones with high boundaries a lot :smile:

Yes though rarely is, I think that theres been one past question where it was 1.73.

If you're in need of a challenge a tsrian has a website and he has loads of hard papers for each maths module but for edexcel spec?
Just search madas maths and look up M1, i think he ranks them in order of difficulty, so you should try the highest rank in difficulty (not necessarily alphabetical order)

There can be coefficients of friction bigger than 1 but it would mean that it takes more force to slide something horizontally than it does to physically pick up the object e.g. something really sticky? As said above this is rare though.

Would someone be able to help me with June 2013 7)iii) please?
I undersand it all apart from why the friction between P and B now acts up the plane? I assumed it would act down as P is being moved up therefore it would oppose this motion?
Sorry if this makes little sense, I found it very difficult to express what i mean!

So does anybody have anything that they are struggling with?

Do you mind helping me with q2 from June 09. Thanks :smile:

Does the direction of the change in momentum matter?
E.g. in the June 2013 question 1ii it gives ±0.09. Does this mean accept either 0.09 or -0.09 or only ±0.09 (with the positive or negative sign)?

Has anyone done last year's paper? In q6 part (iii) how are we supposed to know that the direction of friction changes? Any help is appreciated.
