    How was the ray diagram in P3 supposed to be drawn, I completed failed that


    Posted from TSR Mobile
    Same I knew what the image had to look like but my mind was completely blank on how to draw it so I drew a random arrow for the image and some more random arrows in all directions for the rays 😂

    One Ray went straight through the middle of the lens and the other went parallel to axis, hit lens and the refracted up so it was inline with of on left side. You had to track it back so that the image was formed on the left side of the lens

    I think anyway

    Can someone remind me of that momentum calculation? I've completely forgotten!
    CAR 1 (mass:1500kg) was travelling at 8m/s and CAR 2 (mass:900kg) was stationary, so 0 m/s. When CAR 1 collides with CAR 2, what is the speed that both the car move at after the collision. - answer was 5 m/s.

    1500kg x 8m/s = 12,000 kg m/s (CAR 1)
    900kg x 0 m/s = 0 kg m/s (CAR 2)

    12,000kg m/s divided by (1500kg + 900kg) = 5 m/s

    Oh the one where you had to calculate the velocity after the collision? I thought that one was alright, I got 5m/s

    Think I got that! Thanks a million!

    Hahah there was nothing to lose and who knows, maybe one mark was for realising it had to be upright and virtual? Lol doubt it but no harm in trying 🙋

    There must have been some kind of security breach at aqa , otherwise why would they do different exam papers.Also would they set different grade boundaries e.g one might be harder than the other

    Confirmed. Just spoke to my teacher.
    What was the differences in the two papers then?

    Now I'm desperately hoping that the paper I did was the hard one so the grade boundaries can be nice and low

    It's odd bc I'm pretty sure I did the higher paper too like one of the users further up who put the mark scheme up but I didn't have some questions that he had 😕😕 also shouldn't they make people aware of security breaches?

    Personally, to get 2 marks of why the bus topples over I think you may have to say it has a resultant moment, but that's only a guess.
    yep , you are right. you could say that as well.
