1. (Original post by Zacken)
true, but as its a distance (not a displacement in this case) it can only have magnitude - but I agree, strictly it should be negative

What is this from?
Solomon Paper J

No, it's displacement. You will get the wrong answer if you do not use a negative.
4. Any harder questions/papers anyone would recommend? IAL is good?

I agree, (and said it should be negative), but you are unlikely to be penalised for turning it into a positive (you will simply get a negative height)

Attachment 545123 sorry for the crap quality but does anyone know how to do this question? I can't find a mark scheme for it anywhere
Attachment 545143545145

This is what I got, may be wrong but I double checked it and I can't find anything

9. [In this question, i and j are horizontal unit vectors due east and due north respectively and
position vectors are given with respect to a fixed origin.]
HOW DO I DO PART D????????
A ship S is moving along a straight line with constant velocity. At time t hours the position
vector of S is s km. When t = 0, s = 9i – 6j. When t = 4, s = 21i + 10j. Find
(a) the speed of S,

(b) the direction in which S is moving, giving your answer as a bearing.

(c) Show that s = (3t + 9) i + (4t – 6) j.

A lighthouse L is located at the point with position vector (18i + 6j) km. When t = T, the ship
S is 10 km from L.
(d) Find the possible values of T.
10. It's amazing how watching one Examsolutions video can make you understand something completely xD

12. Is there a difference between IAL and normal A Level M1 syllabi? Or is IAL just generally harder?

IAL are good. But hope you have done the last paper of solomon and the gold papers for edexcel.

IAL is the international syllabus. Whereas the general A levels are done within the UK.
I don't think there is any difference between the content of the specification. IAL is usually a little more tricky than the normal paper

I'll have a go at them, thanks! Any others you recommend?
