CCEA M1 13th May 2013

anyone here doing the physics practical tomorrow with CCEA?

Mine's been moved to Friday.
Our school hasn't enough room to allow everyone to do it tomorrow.

I found the exam was brilliant until question 5 (ii) and onwards. Eventually got part 6 but I doubt the examiner will be able to read my last minute scribble. I feel that question 7 was so difficult due to CCEA's awful wording. I interpreted "Tom exerts a force P newtons, at right angles to the pole, at C and a force Q newtons at D", meaning Q and P were both right angles until part 3. Anyone else have the same problem?

Sorry, I might be misunderstanding what you are saying, but how can you do an exam 3 days after it is supposed to take place?

On Friday there is "Physics AS 3 Alternative Practical (1hr 30m)".

Q2 (i) u = 14.7 m/s
Q2 (ii) s = 11.0 m (3sf)

Q3 (i) 7120 N
Q3 (ii) Maximum number of people = 7
Q3 (iv) Cable is inelastic. Treat lift and people as particles

Q4 (i) t = 3/2, 6 seconds
Q4 (ii) s = (2/3)t^3 - (15/2)t^2 + 18t metres
Q4 (iii) 379/12 metres

Q5 (i) v = -5 m/s
Q5 (ii) m = 4 or 12 kg

Q6 (ii) a = (-8y - 6) (y = coefficient of friction)
Q6 (iii) To get answer, use v = u + at, rearrange to get u = -(a)t = -(-8y - 6)T = (8y + 6)T

Q7 (ii) P = 48.3 N (3sf)
Q7 (iii) Q = 59.2 degrees to the pole (answer could also be 120.8 if you took the angle to the other side)

Let me know what you think! (I might have forgotten about some questions, like Q1 :L)

You see the "state two modelling assumptions" for Q3.

I put

- No air resistance
- Treat lift as a particle

They were my exact words, how many marks would I get?

The data analysis was tricky

i completely misread the first question and couldn't get the relationship, data analysis was okay in my view

Same here data analysis wasn't too bad
