As in 6mg? Because that's what I got for the last question! I got k = 2/3 and agree with strangebannanas answers for everything else. I thought it was a really nice exam overall - lots of show thats. Hopefully I got the 90 ums i need
I think I got 6mg too! How did you answer the question?
Can anyone remember what the very last part of the last question asked for exactly?
Because i didnt get what you guys got. All i did was find tension when P is attached then I found the tension P+Q are attached and found the difference and i got a positive number. Will I get any marks for this??
Also I am getting both M3 and M2 full papers tomorrow so if anyone is interested in having a copy let me know.

it was the instantaneous change in tension, so yeah - find it for the instants before and after the collision and subtract
Guys, the answer to the last question was actually 6. I asked my teacher and shes got a Doctorate and she said no one in the class she knows of got it right.
it is 6mg, my bad
:< I put a 5 inside a square root when I shouldn't have
EDIT: actually it isn't 6mg lol, I think you put a 5 inside a square root when you shouldn't have :P the answer is definitely -8mg/3

How is the change negative? shouldnt tension be greater when the mass is greater so change should be +? I mean just thinking about intuitively..Anyway do you think Ill get any marks if i wrote 6mg and showed all my working? And I am getting the paper tomorrow so we can check.

well it could be positive, but in this case the decrease in speed is enough to make it negative; in the expression for tension speed is squared, anyway, so it's going to have a larger effect than the mass

I just cannot believe it I ****ed up something I prepared so much for, now I have to wait till October and the result won't even appear on my ucas application, what the **** is wrong with the world
