Hi can anyone clarify, I put all my answers to 3sf, rather than leaning it in terms of 3/5g or something would that be ok?

Also I put South West as the direction and also put making 45 degrees with the vertical string downwards, would that be alright? Thanks in advance!!

Question on 4b.

How did you get V = 34 at midpoint AB when it is accelerating constantly?
It said it was constantly accelerating and passed B with speed 34.

However, midpoint AB's speed wouldn't have been 34 would it?

Well, this paper is completely different from the one I sat yesterday. I suppose Edexcel is making different papers for different regions like CIE now?
(I am an international student)

It appears so.

I put my answers to 3SF also, and they always award marks for that, unless they state a different degree of accuracy in the question.

Thanks! Any idea about direction?

not sure about that, i put a bearing of 45^o but my answer as a bearing is wrong as it would be 225^o as a bearing.

Was just looking through q2 and since in the question it states that it is moving up and decellerating, doesn't that mean the resultant force is down? That would mean that part a is the same but b is 50g-NR, giving the answer as 590N?

Thanks a lot for this. Going to get around a 60 out of 75 on this. Great. :mad:

What do you reckon 64/75 to be in UMS? I'm gutted because I KNEW how to do the questions but I didn't check thoroughly enough!

Also, for the last question, I put 3sqrt8*mg/5, not 6sqrt2*mg/5 and also put 'N', acting 45 degrees to the cvertical downwards. How many marks do I get? I used Pythagoras too.

I'm so upset, this paper was so so so difficult. Everyone in my class found it horrible.

Even though I already have 94 UMS in C1 and can do the same in C2 my A has gone now because of this paper :frown:
