Yeh, it was asking for two equations in u and a, and solve them.

How did everyone find it?

All of it was awful 😭😭😭 the worst paper ever
Has anyone got an unofficial mark scheme? and question 1!! So F is directed towards the left and 40cosangle but what force was moving forward
i think f was the moving forward force as it said it was 'pushing'
U was 8 and a was -3 i think for q2
(edited 7 years ago)
i found the paper not as nice as the majority of past ppers i've done, and got a=-2, can't remember the other value
Anybody got unofficial mark scheme for this
Show that question was a nightmare, feel like I've done the first pulley question wrong, think I got a = 3 but I'm sure I've got the minus's wrong

Did you get u = 8
yes, i think i did! :smile: do you know what the pulley question answer is (with the 4 and 8kg boxes)?
I got distance of AB to be 4m... I completely messed the first question up 😣

Did anyone else get 9m for the distance between A and B???


I think I got distance as 20m, took t as 4, because it took 2 seconds to get to A and 6 seconds to get back to A.
Whats the answer to the first question?, I kept getting a negative friction

I thought it was 6m as v=0 when it changes direction no?

Me too!
What's everyone thinking grade boundaries wise? Around 55 for an A?
