72/75... got the thrust as -0.125 at first and thought "That cant be right" so I played around with the numbers and got 2.125N
Do you guys think I'll get 1 mark for using F=ma and showing working for 9e? I ended up making it 1-T=0.3*-3.75

As long as I don't get penalised for not putting in the units for newtons and perhaps if i get error carried forward for question 3 (silly of me as i did it right at first then crossed it out then i wrote a wrong method down thus answers) I might get 60/75 but at least it was much better than the last time I took m1 paper.

[captainaesthetic]

worst case scenario I dropped 10 marks. Still likely to get my A though, would have been nice to muller it..

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?

probably 2 marks. The other 2 would be for using Pythagoras and getting the answer of 5.

Oh no i got 5 the one after that

****, I forgot the 4g on 5(c) as well. I put 0.31 as the answer though, so I wonder if I'll get away with that...even though 3.16 doesn't even round to that

I thought i was wrong in including the 4g was stressing me out all day glad it worked out

For the first question I got M to be -0.3...would I still be awarded the marks despite the negative sign?

Tension is a pulling force, tensions will point towards each other in a connecting object

Thrust is a pushing force, thrusts will point away from one another in a rigid connecting object

Nailed it.

In fairness, I have been saying it every paper since lol

You'de lose A1. Mass cannot be negative.

Arsey for question 4c, how many marks would I get for total distance=area under graph idea (I tripped up on area of a trapezium- stupidly).

[Musical-Ocean]

for the time Q, i wrote 3.0 and 1.3. Will i get full marks?

[cooldudeman]

for 6d) i got the correct time, but i did 2.75 x 7.5j and forgot to add on the -6j. then i found the difference. how many marks would i get?

[Flynn Precup]

How many marks do you think I'd lose for Q7d...I worked out the acceleration for P only which obviously gave me the wrong distance. However, my methods correct...

If you didn't cross it out you will still get the marks; albeit, losing at least 1 for the - sign.

BIG TIP

NEVER CROSS OUT ANYTHING IN A MATHS EXAM UNLESS YOU ARE 100% SURE IT IS WRONG.

m was not mass. It was just a constant.

Yes, any qu where g has been approx to 9.8 should be given to 2sf

If constant is negative, it leads to a negative mass..

I'm an idiot. I crossed it out...

Going to sleep now and I have a busy day tomorrow, so I doubt I will be back on here until tomorrow night at the earliest.
