*** was that(physics paper 3)

[Hamzeh S]

wat was the maximum height of the jet?? was that 4.79m?? anyone got this ans??

nop 1.14 or 1.4 forgot smthn like that you have to do MGH = the energy you calculated at the beginning

i'm not sure. jst giv me da k.e value, n da mass! i'll tell u my ans

 

[Hamzeh S]

wat abt A*

i was talking about an A*

 

[a71]

k.e=1.6065 and mass= 0.14

 

[EpicLol]

no getting medium A's so around 33 or more paper 1 65 and more in paper 3 and paper 6 16 or more just to be on the safe side can be lower though

16/40 in paper 6?!

Paper 1 Im good coz I got 35/40....paper 3 I hope I get like 70/80...and paper 6....yeah....

 

[Hamzeh S]

i'm not sure. jst giv me da k.e value, n da mass! i'll tell u my ans

yup it was 1.14 or smthn i did the KE = MGH so it was 1.14 or 1.4 forgot

 

[IGCSE O/L student]

i was talking about an A*

oh, LOL!

 

[Hamzeh S]

16/40 in paper 6?!

Paper 1 Im good coz I got 35/40....paper 3 I hope I get like 70/80...and paper 6....yeah....

16/20 cause you have to divide it by 2 so around 32 out of 40 70/80 and 35/40 just pass paper 6 and you will get it the curve is kinda of low this year

 

[EpicLol]

yup it was 1.14 or smthn i did the KE = MGH so it was 1.14 or 1.4 forgot

I left that to the end coz I was confused on that questions and I had like 1 min so I just wrote some random stuff with like the formula W = F * d.....
I did bad on that one bit D:

 

[AhmedMans]

Max speed = (350-70)/(45-15) = 9.3
Average speed = 6.7

 

[phro5031]

for the Max. speed , i got 9.33m/s , is that right ??

 

[EpicLol]

16/20 cause you have to divide it by 2 so around 32 out of 40 70/80 and 35/40 just pass paper 6 and you will get it the curve is kinda of low this year

Awesome! I really hope I get an A* Especially coz Im taking the GCSE's a year earlier than the rest of my school is taking them

 

[Hamzeh S]

Max speed = (350-70)/(45-15) = 9.3
Average speed = 6.7

yaa i left its as 6.66

 

[IGCSE O/L student]

yup it was 1.14 or smthn i did the KE = MGH so it was 1.14 or 1.4 forgot

1.15m

 

[EpicLol]

yaa i left its as 6.66

I put 6.67 and 7.78 I dont think its 9.34....

hw old r u?

 

[Hamzeh S]

its is 9.333 because the highest speed was at the straight line where it was constant you had to try them all

 

[phro5031]

what was resistance R?

 

[EpicLol]

hw old r u?

just turned 15 like 12 days ago

 

[a71]

hw do ppl get cambridge award in physics???????????? do they get full mark??
