can someone please upload a solution for Q5.
for part (I) I got 10.5v^2
part (II) 135 x J or something
part (III) I calculated the tension and the work done by the tension and thn used the formula
work done by tension = ke gain - PE loss + work done against resistance, to calcuclate the work done against resistance

The work done against friction was 25 but I don't remember how I got it. Then using the equation -
P.E loss = K.E gain + W.D against resistance.
135 - 25 = (22v^2)/2
110 = (22v^2)/2
220 = 22v^2

Haha I'm sorry to break your hearts, but Lol :p it was such an easy paper.
The whole paper was seen.
I honestly believe the A will be at 40 -44. If the paper seriously was hard, (lmfaowhichitwasnt) , (which IS ALWAYS THE STUPID CASE IN PHYSICS CAUSE YOU NEED AN AVERAGE OF 35/60 FOR AN A IN P2) then POSSIBLY like 38 / 39, but I seriously believe it's 40 - 45.
Haha it was easy for me :p If I don't get full then atleast a 47 +.
IF ANYONE wants to discuss privately just ask haha.

EDIT : On the other hand, P1 was easy but not as easy haha,
I bet I have a high B or extremely low A in it, but inshallah since my M1 was so good it'll cover up and buff out to be an A. :)
Haha Bro
When the result comes i would love to see yours
Btw it was not difficult but not easy as well
I may get around 41-43 iA

The work dove against friction was 25x J
