What was the answer to question 2 part 2 - the position of the particle? I can't remember the value of t you had to use.
I got zero? Cheers for the mark scheme, think I got full marks on section B :biggrin:

Stupid mistakes have cost me 2 in section A, unsure whether I got thise question 2 part 2 right >.>

Pretty sure i got the position/displacement or whatever it was to be 0 as well

What do people reckon the grade boundaries will be?

Awesome, thanks so much. Definitely a plausible answer as the initial position was -2.

and (12, 16) should be right... what they are aasking is the distance between AB, but the distance of B from the origin so (12, 16)

Weren't you meant to work out the magnitude of the distance, which would be 20?

The distance was 20km yeah, unless they're on about a different part of the question :P

Assuming you'd probably drop 1 or 2 marks at most, as it's just one mistake made and the error will be carried forward. Not an expert by any means but I'm sure you wont be penalized too harshly.

would that be for every question do you think? as in lose 1 or 2 marks for each bit i), ii) ect.. or

p.s what do you think grade boundaries will be this year?

Erm I'm not sure, would be harsh to penalize on every question I think - entirely possible that the error will be carried through the question as a whole and you'll only lose a couple of marks.

I think this paper was a little easier than the Jan 2012 paper and that was 54 for an A so I'm hoping it'll be something around 57-59 at most for an A. A lot of people struggled with section B though so who knows :smile:

Yes In my post I said pythag. Which would give u 20. I just couldn't be bothered to type it up there :smile:

hey guys!

for question 6 (i) i got 4.37m and i said the ball would go over the crossbar. how many marks would i lose there?

my method:

1) found the time from the horizontal component
2) sub in the time i got into the equation of the vertical component

thanks!
