How did mechanics go?

[Saturation]

5!!! yesssss!!!! that means the coefficient was 4/7 right??!!!

YESSSS!!! I really thought that I got the tension wrong!! :Yahoo!: :Yahoo!: :Yahoo!: :Yahoo!: :Yahoo!: :Yahoo!:

Thanks for confirming!!! :Yahoo!: :Yahoo!:

 

[kakarocks]

So you HAD to divide 9.99 by 2 to get the tension X_X . guess ill loose only the accuracy mark ? not the method one right ?

 

[abrraza]

for q1 i i put it dwn as 4920 3sf
would i loose marks?

yeah thats coorect

Apparently yeah! I wrote 10 at first, then had a funny feeling, and as the examiner came to collect my paper, I just scratched out the 10 part, and left 5!
And yeah, you'll get the method marks! :good:

The gt will be high as most of the candidates in my centre are getting full marks...

 

[sadabrahman]

I am expecting full-marks inshallah...

 

[ks136]

can we find tension by lamis theorem

Guyz these r the answers for M1 paper. You can chek yr ans... :evil: :evil: :evil: :evil: :evil: :evil: :evil: :evil:
Q1. i) W.d=4920J
ii) Power= 97.1W

Q2. H=4.25m

Q3. 1048
1360N

Q4. Theta = 21.1 deg
F= 11.1N
R=12N , 30 deg below horizontal.

Q5. Set of values of T 0.7<t<1.2
velocity of Q=-1 P=4

Q6. T=5N
R=7
f.f = 4
coeficient= 0.571

Q7. i) t=100s
s=110m

ii) at t=64.05, v=1.16m/s for both (show)

iii) a=0.312

 

[oohlala]

r u sure about the answers?

 

[zulqarnain]

grade threshold would be quite high as it was quite easy and the last question was a repeat!

 

[abdullah12]

In Q5, I wrote the time at which velocities will be equal and forgot to substitute the time into eq to get velocity..how many marks would I lose??

And in Q4b, I worked out "R" instead of directly stating..is that OK?

whats the authenticity ? in q7.. ur acceleration is wrong! in q6. ur R is wrong......
