Re: Aqa mm1b!!The best things you can do is to go through some past paper first,and then post some questions which you don't understand,so that we can help you...
The machanic paper is not difficult actually,just practice more you will get an idea how to do it.As all the question type are repeat and repeat.
some propular like:suvat,momentum,connect partical,projectal must be in there.
You don't have so much time,so advise do the pp from 10 jan to 12 jan.
I think this would probably help you to improve.Do pp can always help you to solve some stuff.
so work more hard

Re: Aqa mm1b!!6. (a) t=4 θ= 0 (because its horizontal) and x= 1000(Original post by shannonmcnamara)
can someone please help with this question?! exam is tomorrow and i'm panicking!
use x=Vcosθt 1000=Vcos(0) x 4
1000=4V V=250ms-1
(b) y=Vsinθt-0.5gt^2 + h
0=(250sin(0) x 4)-(4.9 x (4^2)) + h
h= 78.4
(c) Vcosθ i + Vsinθ-gt j
250cos(0) i + 250sin(0)- (9.8 x 4) j
250 i -39.2 j
magnitude= 253 ms-1
(d) x= Vcosθt
1000=253cosθ x 4
θ= 8.91
if you use the rounded 253 value you get 8.83 which is also accepted as the right answer!
its all using the equations
hope it helps
