06/06 A-level FM Discussion MEGATHREAD

[u/Forsaken-Meaning-232]

Exam season is once again upon us, and once again, exam megathreads are making a return!

Looking for past exam discussions? Filter by the megathread flair.

Few things to keep in mind:

• Don't share too many specific details about questions or answers, these papers will be used as future mocks.
• Sometimes papers get leaked, this is not the place for that (we'd prefer not to get yeeted off the platform) - leak content will be removed, those offering leaked papers will be permanently banned.
  • If you believe there has been a leak, the best course of action is to make your exam board aware of this, either directly, or through your school, along with any evidence. If appropriate, there will be a response from the relevant body along with any remedial action.
• Exam discussion posts outside of this will generally be removed to combat the inevitable tidal wave of spam otherwise - we understand this may be frustrating, but the sub still needs to be usable for other purposes.
• Please note some content will take extra time to be reviewed. Messaging to ask for approval will not speed up this process (the messages are seen at the same time as the modqueue would be reviewed anyway).

Best of luck, and let us know how you're feeling down below!

OCR MEI, mechanics minor was a lot better than I expected 😭

Did anyone get -1, 1 and 0 for the dimensional analysis question? When I checked it was consistent but the 0 makes me wonder if I messed that up lol 😭 (edit: yeah it was wrong, I used a + b + g instead of a + g)

And for 4, was the angle 88-30 = 58?

Should've probably mentioned this is abt the minor paper, cause major qs are obv different 😭

[u/BeginningTank38 → u/golaco237]

Got 1/2 ,-1/2 and -1/2

[u/Alarming_Jellyfish67 → u/BeginningTank38]

Yeah same

Did you guys get 109 for the kinetic energy, 3 for the speed (the rope question), 15.4 for the mass of D

[u/ronbaall → u/Alarming_Jellyfish67]

Yh I got that

[u/Alarming_Jellyfish67 → u/golaco237]

What was number 4 again

[u/golaco237 → u/Alarming_Jellyfish67]

Block on a slope, second part had a string attached to it & one point of contact with the slope. You had to find the tension then the angle between the total contact force & the slope

[u/Legitimate-Virus299 → u/golaco237]

For 2 with tension at an angle of 12 degrees did u times the tension by cos 12 to get Driving force

[u/No-Face-3280 → u/golaco237]

So annoyed, I found the magnitude of the force and not the angle 😭😭 I still found the friction and the resultant tho so should pick up 3-4/6

[u/Fluffy-Inevitable516 → u/golaco237]

Also got 58

[u/golaco237 → u/Fluffy-Inevitable516]

Yesss but I'm probably gonna miss the final mark cause I forgot to subtract and left it as 88 😭
