Physics unit 1 6PH01 discussion :)

[MarvinM]

How did you prove that the drag force is 0.01N..........??

Is this the one where it said "you may consider upthrust? Or something like that

 

[MarvinM]

soo yes...here we go...
wat was the CO2 emision???
wat was the horizontal distance covered by the ball???
wat was the time taken for energy question???
actually all the calculation part...i need answers!! im way tooooo scared...

For the co2 emission I got like 0.78 , which is most probably wrong
I think for the horizontal distance I got like 206-218 (can't remember )
Which energy question ?

i got the drag as 0.0064N

for the carbondioxide...thing wat i did was i subtracted the emission values for both the velocities..and then i think i multiplied by 3....sooooo i got sumthng like 2 sumthn......
the enegy question...sumthn abt 540kJ and 25% efficieny...and it said to calculate the time???

 

[blossom edward]

hahhha

i got the drag as 0.0064N

hahahahhaaa...i divided 0.02 by 2...god knows y??? such an idiot i am!!

the enegy question...sumthn abt 540kJ and 25% efficieny...and it said to calculate the time???

i got the time as 612 minutes

 

[blossom edward]

i got the time as 612 minutes

yeah...............that right lucky u :/

Which energy question ?

horizontal distance wasnt tht 184 m or smthing?:O

 

[Ayesha B]

i got 0.04 for that. btw i felt this paper was harder than the jan 13.

NOOOOO, nonono, I did the Jan 13 and I'm SO GLAD I resat. Was this your resit or first attempt?

 

[Vj Destiny]

It was worst :"(

The problem with that CO2 question was that the graph said something like the Co2 emission kg km , so it was per kilometer . So you had to calculate as well how many kilometers they travelled an then times this by the co emission and amount of cars , thats what I did

 

[Aaron Rodrgp]

sexy paper but tooo long

 

[Ayesha B]

Oh gosh the time limit was the main issue I guess. that 7 degrees and 1 ms-2 was just terrible.

Still sososo glad I resat this paper. Atleast it felt like I was doing Physics. Jan'13? Don't ask

i got that aswel

 

[Mufaddal]

The last ten minutes i was just writing anything that came into my head...the paper was sooo long!

 

[Aaron Rodrgp]

i got 185

 

[Ayesha B]

LOL same. I just couldn't leave the space empty so I guess I did the equivalent to making a few pen marks here and there.

 

[Ahmeday]

i got 185

and wat abt the time of flight?

 

[MarvinM]

The last ten minutes i was just writing anything that came into my head...the paper was sooo long!

Hahahah same! The examiner will think "what on earth was he thinking"

662 minutes?? is that what you got?
