Edexcel Further Mathematics Mechanics Exam 14th June 2023 [Exam Chat]

Poll

How did your Edexcel Further Mechanics exam go today?

Hey guys, thought of opening a further mechanics thread, so I am going to start with this:

Does anyone have any questions that are not from a textbook/past papers/madasmaths and is willing to send them on here?

Nah mate, i dont have any exam questions but what do you think the question structure will look like

Idk hopefully similar to past papers tbh, and not something too difficult

Collision in two dimensions (from MEI)

16. A red ball is stationary on a rectangular billiard table OABC. It is then struck by a white ball of equal mass and equal radius with velocity.
u(-2i+11j)
where i and j are unit vectors along OA and OC respectively. After impact the red and white balls have velocities parallel to the vectors -3i + 4j, 2i +4j respectively. Prove that the coefficient of restitution between the two balls is 1/2.

Happy to post my solutions to these, but searching the STEP year and paper number will bring up solutions online

For me it's mainly timing - so probably just as much practice as possible in timed conditions.

Thank u so much for these! Yeah I actually did not think about doing STEP questions

Does anyone have a bunch of oblique collisions questions where you have to use vectors and the dot product??

I don't know if it'll be much help but I have a copy of the AS further mechanics from this year if anyone wants it?

Yes please would you be able to send it? (idk if you are allowed to or can get disqualified tho)

So I have a question about when finding the range of values for e. Everywhere I've seen it its been 0 <= e <= 1, however in the 2022 paper I've just finished Q5b and Q8a have the lower bound as 0 < e. and Q5 even says "Need both ends of the interval. Must be strict inequality at both ends". What are we meant to actually write in the exam!

Does anyone know of any other specs or other resources that have a similar style to edexcel wherein it is mainly modelling questions

For question 5, e can’t be 0 as if that was the case speed of separation would be 0 so they won’t separate. Therefore there wouldn’t be a second collision.

For question 8, it says that the ball bounces of RS. If e was 0, it wouldn’t bounce and would just roll along RS, so e must be greater than 0

You need to analyse the context - in some cases e could be 0 and in some cases it cant
