excell

68/75 but maybe some working out marks on the last couple of questions, not sure.

Looked through the answers

Should have it all right except for the tension and thrust parts of the last question. Disappointed I didn't get the tension. Can forgive myself for not getting thrust.

Worried I might lose marks for having 4sf in my answers for the time in Q5 where I put 2.988s and 1.298s

Did the exact same thing. :frown:

Got the method completely right, but forgot the weight force acting downwards and just considered a resistive force of 5000N.

for the vectors question part d), would you be penalised for putting the distance in terms of j?

For the bearing, can you say 58 anticlockwise?

Hmm so I ****ed questions 5 and 7. But I think not counting the ones where you prove stuff, that's a B maybe an A? :s-smilie:

I deducted 1 for putting down 300 instead of 302 degrees and another for writing down the actual value of time for when it decelerates on the speed time graph rather than T1.
I'm happy :smile:

Done the same

forgot the 4g

but we should get atleast 2 marks for tht if the working was correct 1 for F=ma and one for using suvat

Does 058 anticlock not work? And for the last 4 marks on question 6 how many method marks can i expect for finding the time that theyre due north and
Subbing it into a position vector formula?

Sorry to be a party downer, but I found some questions a bit tricky and I'm normally a whiz at maths. so for anyone who's saying "this was so easy"... sh.

also, it stumps me how m1 grade boundaries generally tend to be one or two marks higher than c1?! anyone else find this strange?

ps - why neg? thought people would be relieved to hear not everyone found it absolutely fantastic
