Arsey's Edexcel M2 S14 Model Answers

Arsey please get one of your minions to do fp3 thanks for all the solitons thus far you are the man

Arsey I'm a little bit panicked now could you tell me what you think(I really need A* in this):
Impulse I did wrong with the plus and minus and got lambda=-1/3.
The angle but for the centre of mass I annoyingly did right but imagined the lengths of the triangle they gave me were both 6a(so did=45-theta).
Finally the worst one, the 8 marker for distance AB, I used the wrong time,0.525, as I found it using v=u+at and didn't use the negative version of 'v'. How many marks do you think I lost? Particularly on the final one?!

haven't seen the paper yet, no one at our centre was doing FP3 this summer, will see what I can do tomorrow.

Hey Arsey,
Do you reckon 70/75 in this paper would be 94 ums?

Here are my solutions

I thought it was a pretty easy paper

I would be prepared for high boundaries

Thank you so much, can't wait to hear your thoughts on that monster

70/75 is not even 94% raw so it's impossible that will be 94 ums given how easy this paper is. 90 ums is still quite possible though. If 65 is the A boundary then your mark will be 90 ums. I think the real A boundary will be between 61-65 (broad range I know lol)

Easy paper.

74-100
71-90
68-80

I disagree with your answer to 3b, Arsey; you found the angle between the downward vertical and AC, not AB!

me and many others got what he got i think he is right.

loool but you got balls for going against arsey nice

edit: you need to find the angle you are talking about in order to find the angle between AB and if you go back to check that is what he did

thats too high I reckon

75 - 100
69 - 90
63 - 80

Too low.

75 - 100
70 -90
64 - 80

any chance of haveing the m2 ial answers up by today?

They need to be in equal steps, so it's
75 - 100
70 - 90
65 - 80
