Fairly sure most of these are right. At least, they're almost all the same as what I got (the answers harryhlchan put)
(edited 7 years ago)
Wasn't the angle for 2ii the angle to the vertical making it 90-your answer.
Yes it was.

Yeah) You are correct)
Does anyone remember what the question 5 was about?
Mechanics is such a joke 😫
For ques 6.i. Isnt the tension before releasing 0.2*g = 1.96 N
Thats what I thought, then I think i got 1.69 for the Tension after.

I believe I got 1.69 as well and T=0.2gsin(30) for before release

I got 1.8095 for the tension afterwards but 0.2g for before :smile:

Same, as you have to resolve tension from about Q and about P.
Hi, I made a mistake on the 7 marker when getting P. I used the 25 instead of squaring it as I thought magnitude would be square root of 25. I got P=2. How many marks would I get?

Didn't you have to consider the fact that it was inclined? Meaning that g was acting at an angle?
Any guess about grade boundries?
Did anyone get (I think 6iii) about the contact force when P was moving? I had already worked out a contact force from the previous parts of the Q based only on the weight of the particle, but feel like there must have been more to it than that. Got like 1.69 or something

I'm pretty sure I got 1.69 too and so did other people! The contact force is the resultant of R and F (I think).

I got that too but can't be right can it? That would have been way too easy for 3 marks
