Physics unit 1 6PH01 discussion :)

[abdul aziz123]

Answers I got:

12.4 seconds
183.7m
CO2 emissions 0.75kg
Power: 3,057,065.2
Time to burn 25%: 36,000 something seconds
Anyone else get similar answers

power i did using both methods ! K.E/TIME I GOT 3MP ! and i used f=ma and p=f*v i got 60000! dunno why :/

Does anyone remember their carbon emission question?

I only did the Power =force*velocity.......

 

[ALevel96]

I only did the Power =force*velocity.......

Ahh it's 1/2mv^2 divided by 2.3

i forgot most of my calculation answers shit...can u check my hookes thingy answer please?

ohhhhhhhhhhhhhhh god.....................

I replied to it previously not sure if mines right though haha

 

[jackoo123]

Mine

Does anyone remember their carbon emission question?

was 2.something

 

[cardude456]

Does anyone have the unofficial mark scheme..........................?????

couldnty we use f=ma and then p=f*v!

 

[cardude456]

couldnty we use f=ma and then p=f*v!

Thats what i did........

 

[ALevel96]

I did this and got 0.75kg:

Travelling at 5 m/s for 10 minutes means a distance of 3000m emission were like 0.26kg/km therefore times by 3 because 3km and 3 again because 3 cars.

Then at 16m/s emissions were something else times that by nine and subtract the two

no i mean check my answer hehe

You might be correct actually however a few people at my school got 3,000,000 and something

shit i assumed for one car not 3...so i ll lose 1?

 

[ALevel96]

What

no i mean check my answer hehe

What was it again aha

 

[abdul aziz123]

w

Thats what i did........

hat did u get? i got 6MW!

 

[svenas]

What

What was it again aha

i said it didnt obey cauz if we ll extend tht straight region it wont pass thro origin and hookes law sates tht force is proportional to extension - can i get 2 ?

 

[ALevel96]

Yeah I said something along those lines should be fine! The important thing I think is to fact that the whole line isn't doesnt show direct proportionality

 

[ALevel96]

Where do you think the boundaries will lie for this exam?
