everyone's version of 'tough' is different

According to you?

for keeping the block equilbrium a frictional force must act on the block in the right direction
so 6.1+5cos theta=f
f=7.5
2)f=ur
r=12.5
3)7.5-8.6-5cos theta=ma

I don't knw how to resolve it :S

According to you?

well i think v.43 just because they have lower curves but personally i dont see any difference

Emm, I registered and there's no email in my inbox.

hey is there any general difference between difficulty level of the differnt varients or they are same in this respect? :\

Q1 part ii. It's a bit absurd but just tell me. :/ Please! :')
Pie-man guess u have done this one?!

I personally think v43 is a bit stupid! with those semi circles. -__- i like my variant better. Actually i just started v43...lol..not sure.

well the past paper i have is for v.41 and if i go for other variants i choose v.43 cause i like the number 3 more than 2 .... i'm a complex person

Hey! I like the number 2 better than 3. Or maybe I'm just making it up cause you mentioned it...haha ;P

 

[Silent Hunter]

Hows preparation people? Generally speaking what type of questions you people think are difficult ? .....

i've reached the point where i have no ability to think but you have to use Energy to get it cause you have height and mass and at point A K.E. is zero....i think, but i still might be wrong ... i'll just go sleep
