In what way could they come up?

Posted from TSR Mobile
mixed exercise 3E has two questions
2. (Original post by MLogan)
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.

What have you done so far?

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

how would you write the displacement vector OB in terms of i and j?

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

Crikey, haha! He was probably doing that to scare you all Having said that, I have a habit of over-complicating questions...
19. 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
