For the velocity-time graph question, was T = 8.75? I know I set up the simultaneous equations correctly but I think I may have accidentally divided by 2 instead of multiplying while solving...


yup t was 8.75... most of our year group agreed on that

I got this. Glad someone else did too! Was sure i was right... If anyone has the full question I think i'd be able to put some working in and show it
Hey guys, got 2 questions :

I did question 7 but there there were lots if crossings out in my awnser so i had to to copy down my awnser for part a on a seprate page. Will the examiner mark this?

Also i used the right method but messed up in arithmetic. How many marks would i get for the method? I got 5/3 i + 5/3J
