    Yes and yes
    yeahhhhhhhh, and did you add the velocities for the last part of question 7.

    and what did u get for the angle of the lamina ??

    I messed up the 2D motion one and got the first bit wrong by a wrong calculation although the rest of the wuestion had the correct working but wrong figures?im guessing no error carried forward?
    Also any ideas of grade boundaries?
    I found it very hard hope everyone ends up doing really well!

    I did the same, ended up just crossing everything out and putting 20... There didnt seem to be a logical method
    at least you got the marks, I didnt even realise it was 20!

    For that horrible centre of mass q, after 30 mins I got the distance as 1/2m and the angle at 10.9 (from memory)... Can anyone confirm these?

    i think for the distance one you were meant to integrate the velocity between the values of t=0 and 4, the answer was like 208/3???

    Love how writing 20ms-1 for 3b got you 5 marks, I did all the differentiating and stuff to get 4.5 which is totally wrong
    I thought 4.5 is right as if you sketched the graph that was actually the the highest speed.

    what i did that as well - how can a five mark question result in the answer 20!

    Did the same at first, you had to integrate from t=0 to 2, then from t=2 to 4, because it changed direction... Came out at 24

    i got 0.5 as well but i got a different angle

    I'm only going from memory, the angle was definatley about 10 degrees, well, at least that's what I got

    Ask edexcel but tbh I am really unhappy that you could get 5 marks just by looking at the equation

    @Jack I thought the same as you, I didnt even think to just look at the equation and sub in 0.

    I lost marks on this question, the angle question and the question right at the very end, 14 marks lost, and to think I wanted 100 UMS lol
