Edexcel A Level Further Mathematics
Hello ,
I have done this question and got the correct answer however, i used physics knowledge E=1/2Fe in order to get the answer .
Would i be panelised for it?

It sounds the obvious way to do the question and fm does cover elastic energy so its on the spec. Writing EPE as 1/2*tension*extension is just a simple substitution.

I get what you are saying but I've never come across 1/2* tension*extension on any mark scheme or even in the content book

Id not overthink it. The question seems 10 easy marks approached the right way, so tension=50 (3:4:5 - pythagoras) and epe = 10=1/2*50*e, so length=0.9.

EPE is essentially work done so the integral of force wrt distance. So thinking of it as 1/2*tension*extension is arguably closer to the definition than the usual form of 1/2Ke^2. You could have solved for both K and e using the tension and energy equations, though thats simpy unnecessary for the question.

But you have come across 1/2 ke^2, right? You can show a brief derivation of 1/2 Fe starting from 1/2 ke^2.
Yeah i have
So what’s the answer and where is this question from?

question is from pre 2017 spec , so from M3 module but i used it to revise for my further mechanics maths alevel exam.

Oh okay thanksss. Pretty straight forward question for 10 marks lol I wish further mechanics papers were still like this haha

Just something that popped after you replied on the physics gcse you do the
EPE = 1/2 force * extension
http://chubbyrevision.weebly.com/work-and-energy.html
so EPE is the area of the triangle (integral of force with respect to extension) but as the force is k*extension, its the usual 1/2ke^2

100% i got a pretty sweet exam question booklet its all the exam questions split by topic and it makes everything 100x smoother when revising.
Can you share the booklet pls if udm?

I don't do A level Physics so I have no idea how else you would do this other than doing what I've done. The only other thing I would say is that by the looks of things, this is from the old spec because this is Normal maths and I believe that strings and springs used to be in Normal Mechanics? A telltale sign of this is the resolving stuff and the fact that this question is 10 marks. In FM1, I would say max marks for this would be 5 or 6.

I might be wrong with saying that this was in the old A level but there was a massive rejig of topics in the new spec.
