well you dont need the original position, i just used that formula to find velocity instead of location

i used velocity and acceleration(t) instead of location and velocity(t)

m and m/s vs m/s and m/s/s
Ohhh
didnt know you could do that thanks!

Wow yeah that is quite weird! Although, it may perhaps not be the full mark scheme, so it might allow 5/3 in 3.s.f?
That's what I thought but
3. can someone tell me what r is ?

You can choose what direction you want to call positive
But the question tells you they're moving in opposite directions! So it doesn't make sense for you to label them as both positive!!

Also why have you used -33/mu ??

5. Need help on 8d june 2005 please, don't understand where the mark scheme got "Distance travelled by 2nd player = 13.8 – 6 = 6.8"

R is the final position vector, R0 is the initial position vector

current location depending on t

look at my workings out that i posted before.

as i said before, if you use an aproxamation such as g in your answer, you have to round.

In jan 2011 you were doing vectors which is fine.

in june 2011 you assumed that gravity equals 9.8 so you must round to 2 or 3 sf.
it says this on the front of the exam paper
Ohhhh, got ya now, thanks! This exam's more pernickety than I thought, oh god

P keep moving in the same direction, just watch examsolutions video if you dont understand its hard to explain in text.

Impule acts in opposite direction of motion

12. um hi, i have a question from a pulley section of the paper... https://drive.google.com/file/d/0B1Z...lHRkVGMUk/view - it is question 5b and the markscheme says the distance is times by 2 so the total distance is 0.6 but i dont understand why it is.

13. What do you do when one vector is North-west or South-East etc of another vector?

when northwest vector is -i + j

so get the i components equal to -m
get the j components equal to m
and solve

You know for that question you answered just know to do with being parallel to vector i? Did you get t = 3?

Interesting...

Maybe they recently included that because they didn't put that in the papers I was using

2014+ , altho this has always been the case since 2001

the one where the guy forgot the say which vector it was parallel to in the OP.

And I literally find this out the day before the exam I probably would've lost a lot of unnecessary marks in the exam tomorrow if I didn't know this, I'll thank you again I hope there aren't any more of these subtleties I don't know about...
