Physics P22, How was it!

[Sriyog Sharma]

How was your paper ?

I don't know some people are saying that they did really good. I didn't do 5 marks , and made many mistakes on the first question. But rest it was pretty easy.don't know if i will get A or not ? I wish the threshold is really really low.

what did u guys get for the resistive force qs?

Force=Drag Force So force= that equation you were provided in the first question. I messed this up :/

well same here..3 marks gone

well same here..3 marks gone

which part is this.. is this the 1 for showing that the velocity is approximately equal to 7?

REALY EASY PAPER

what was the value for you acceleration of the mass on the spring??

 

[cowarrior]

3.8

 

[geek101]

3.8

i got 3.7something close!

 

[cowarrior]

hehe congratulations..!!!! 3 marks right??

you subtracted the f spring - weight to get f net and then used a = f / m ???
yep i think...dont remember though

 

[cowarrior]

F=kx . F=ma . you have mass given and extension is known too. Oh, k is also given . So using F=kx and f=ma you can easily get the answer.

dude are you sure we had to minus the weight of the mass
I think I forgot to do so
would I get 2/3 ?

i dunno...but the weight would still act downwards opp to the direction of acc. so i think we have to subtract the weight. hope ya do.

Question1 graph ?

I made this not sure

i dont think u needed to subtract. cos in f=kx the f represents the net force already.. hmm i dno

Hey guys, how much marks are you all expecting?

Hey guys, how much marks are you all expecting?

45-50 what about you

 

[raamish]

hey guys what will be the threshold. Should it be 40 or 40-45?

 

[Silent Hunter]

what were the forces acting on the spring while it was just released? weight and upwards tension ?
