Is it me, or was that stupidly easy?

Yeah, I thought it was. Nice exam.

Phew, at least one other person thinks so.
Luckily i had done two of the EXACT same questions, 4 and 8, for revision, so i just wrote it down for tonnes of easy marks.

This is the one that everyone was worrying about :/

Yeah, same here. But most people found it hard apparently.

Only question I found (I was the first reply in this thread) was question 6, merely because I messed up my formula in the second part of the question. Everything else I found strangely easy, the last two questions were done in 10 minutes

Question 6?
Sorry, i cant remember which is which.

Something on an inclined slope, you had to work out the frictional force (got that) and the distance it moved before coming to rest (don't think I got that).

i thought that the "train" question, question 7, was dodgy to find out T....
also that question about the diver 5 metres above wat? from the springboard or from where she jumps.... some of the questions were badly phrased in my opinion!

Question 7, T=98 seconds

Basically you were told the train overtook after they'd reached maximum speeds. So you took the distances travelled whilst accelerating, and calculated the distance moved up to the overtaking point. Basically by putting their distances equal you are working out at what distance they overtook, and stuff. I can't explain it now, but 98 works out fine

i remember that question

the working was

30(12)(0.5) + 52(30) + 30T = 60(24)(0.5) + 60T

180 + 1560 +30T = 720 +60T

1020 = 30T

T=34

However as in this model I have taken the value of T beginning at 64 seconds

34 + 64 = 98

(however as i managed to write down in the actual exam 64 + 34 = 100)

i didn't have enough time to complete all the questions... wasn't sure how to find the distance moved by the particle on inclined plane.

luckily, grade boundaries are lower than in pure or stats,

for the question working out T, i understood the question as being that B overtook A when it reached its maximum speed, so i got T=64 i think, i was prob wrong tho. the other one, bout the diver, it was terribly written. i did it so that the diver went vertically upwards and then down, because the question was phrased as sayin he "didnt hit the board", but it was only a 3 mark question! question 2 was prob the trickiest impulse and momentum question ive seen. they normally very easy
