    To work out P.E gain, K.E loss. Like the questions on pg 96 qs 46
    I don't think I've ever done one of those questions :-/ How hard could it be though?

    Wouldn't you get two different things depending on each particle as one gains PE while losing KE but the other loses PE while gaining KE and as the tension is constant the acceleration is the same so it would be possible to link them together? Just guessing here.

    I understand how to find the angle but i'm just unsure of how to find the vertical velocity.

    Well, you know the angle. The horizontal velocity stays the same throughout, so you can form a triangle and use SOHCAHTOA to work out the vertical velocity Geometry, that's all!

    Some is. But I think you'll agree right-angled triangles aren't that bad

    That's true, my teacher did a chapter 5 question using just geometry and he had inverses and square roots everywhere in his solution, it was vile but got the correct answer, then I did the easy method and got it in 5 lines, he wasn't too impressed

    My school did M2 in january and I'm so glad I don't have to resit it, M3 is not pretty though, when they have the questions which combine different topics (e.g centre of mass + SHM) I'm powerless

    Well his motto is diagrams unlock understanding so it didn't surprise me at all and I'd rather do it the shortest method I could use, I don't really like writing that much
