AQA A Level Maths Discussion Thread - 2018 Edition

Hey guys, I thought I'd make this niiiiiice and early so we can all share how we're preparing for our Maths exams this year?

Mechanics 2
Date: Monday 25th June 2018
Time: Morning
Duration: 1 hour 30 minutes
Days to go?: 1 :crazy:

Probably the most important way to prepare for maths is to do plenty of past papers! You can find the more recent papers here and the older ones here.

Also, Physics & Maths Tutor has some good resources for revision - everything from revision notes to questions on specific topics. You can find the Mechanics 2 materials here.

Good luck with the preparations everyone, let the countdown commence!

How many marks will I lose for forgetting to include the distance for the frictional energy in the question about the child..
1-2?
I got the rest of the paper correct I believe. What did people get for the time for the speed to increase from 18 to 22

I think I got 13.0s, not sure how many marks you’d lose - how many was it out of?

Decent paper overall, last question was almost identical to the last one on the jan 13 paper

3 if I recall correctly.
That’s odd I got a much larger value for t :frown:

Yes that’s exactly what I thought of the last question.
What did you guys get for the value for x at maximum v

got u = root (ag)

Oh my god I completely messed it up. I hadn’t done the paper on which the last question was similar so I just didn’t have a clue I also blanked on question 6 as well. Need an Unofficial Mark scheme rn :frown:

Some of my answers I can remember:

x̅ = 52cm
ȳ = 40.5cm
m = 2.67kg
μ (min) = 0.184
t = 30ln(11.4/(3g-v)) -> when v = 22ms^-1, t = 13.0s
u = 4sqrt(ag)
u : v = 2 : sqrt(5)
v = sqrt[(40-2μg)x - 20x^2)]
r = sqrt(3)/4 * L
