i cant recall da nswer horiz distance is 0.3 m i think n time is 0.6 sec


How did u measure the distance? you used a ruler right? So I measured the horz distance with a ruler and I got 3.2cm which is 0.032m.

Time for the horizontal motion would be same as time for vertical fall (x to y) so i used t=6/20 seconds..isn't it?

I said v against r2 and find the gradient gives the viscosity.


I said plot a graph of Viscous drag on the y-axis and 6*r*pi*v on the x-axis and use the gradient to find viscosity.

dat da time taken fr half da motion of da projectile u must multiply dat by 2

im nt sure of dat value bt u mst first measure da vertical distance frm ruler x to y den use da distance calc in prev question to make a scale den convert da horizontal measurement into da real horizontal distance

I assume we were told only to deal with the falling distance just (x to y) ..not like like that of the ball going up and then coming down so were not required to find the time of flight or something..

O yeah i did like that..what did u get as horz distance?
i only measured half of the distance and I got 1.7cm and not 3.2cm then I used s=ut ( with time as 0.3 from the previous question) is that correct

no unofficial mark scheme?
Did any1 else get 7.9x10^-14 ohm metres for the resistivity on the last q?

And did any1 get 0.77 for the efficiency of the electric motor q? The current and voltage were given along with the mass and height the weight was lifted by...

I don't even know your board ._. You can check the main forum page though you'll find it easily.

Wait for grade boundaries dude

Sorry then I don't really see another thread :frown:
I'm hoping for at least 50/80 , paper was Medium in the beginning, then it got hard in the last few pages so I'd rate an A with 49-51 /80
