How was 9702 W15 paper 22?

[The Sarcastic Retard]

It is. You can use cosine rule to get it. I ******* measured the length of the scale and got 11.4 so I am losing a mark here I guess I am not sure. coulda used cosine rule I always used that fml
I did prove T yes
0.489 I reckon

So how u know answer is 12.12??
How did u do it?
I got 0.11 though. :/

dude, 14.0 and 8 and 60 degrees between them use cosine rule
wait there was sth 0,12 and something else was 0,489 so not sure

I dont get it.. m confused.

Wait, are you supposed to determine the resultant velocity by drawing a vector diagram or by calculation?

It was not specified.
I did it by formula and got 12.12 wbu?

I did it by drawing and got 12.2 or 12.1

w14 p23 A was outta 45 btw

I just did both xD
I measured 12.2 for both apparently, I must have rounded the calculation method wrong, was panicking..

 

[ahmedish]

Highest A ever in AS was 97/130

 

[Albert Lianto]

And for ratios, if say I get a decimal answer n, do I say n : 1, or n only is fine?

w14 p23 A was outta 45 btw

But 22 never crossed 40

Means?

What was the Time For the Kinematics Question , I Had problem in that question due to less time because i solved that question at the end.

Oh didnt check that. but dont think it'd matter really, if the exam was easy they are not gonna say we cant put it above 40 cos it's v 22

1.2 or 1.6 I guess.

i got 1.2 im not really sure if thats correct

True..

 

[ahmedish]

However, w14 v23 is way easier and shorter, our exam is probably 36ish

 

[The Sarcastic Retard]

why?

Think it was 1.2 seconds? Initial speed was 3.6 ms-1 and acceleration is 3 ms-2?
