What about the question where , with a simple method , you can measure the centre of gravity. What did you guys put?

keep your finger at the estimated position and check if the cue ballances perfectly

i wrote adjust on pivot until its in equilibrium, correct?

 

[Aaron Rodrgp]

aldo for the last question i only like related tht uniform acceleration up to a specified time, then uniform deceleration...in tht way , will i get a mark here?

im really nt sure :/

seems legit

 

[Aaron Rodrgp]

It was T=W/3sintheta

it was actually costheta, coz the angle was given towards the vertical

 

[svenas]

seems legit

so is ok?

 

[svenas]

seems legit

i wrote 3W/costheta

 

[Aaron Rodrgp]

i wrote 3W/costheta

it should be T = W/3Cos@~

 

[svenas]

it should be T = W/3Cos@~

shit haha, what was the answer for why it was a minimum power?

 

[svenas]

shit haha, what was the answer for why it was a minimum power?

I wrote coz it still hv to go uphill..

i worte the fact the as the ride goes faster, there is more air resistance to compensate for

 

[svenas]

i worte the fact the as the ride goes faster, there is more air resistance to compensate for

my answer makes sense?

 

[Zahidur]

Minimum power could have been due to the fact that no system is 100% efficient so more energy could have been needed to accelerate the ride to the desired speed?

i did the whole paper wit my calculator in radians mode

-___- sure? or just a lie to cover your ass??

well...u din take the exam..so ur not supposed to b here -_- n i noe that its a rumour spread by A DUMB ASS!!!

Does anyone has a unofficial markscheme for this paper?
