no... infact the only paper i do have is 2004
but if ur having difficulty with a particular question why don't u post it up..hopefully someone will be generous enough to help out
as for me .. i still havn't studied ideas to implementation.. i have some major cramming still ahead

i didnt want to coz id look dumb but maybe i should....
see i read 3 versions of space summaries...i was like "thats down pack" and was going to move onto motors when i was like hmm....lets look at the 2003 trial and see if i can do it...
(im sure it will be easy for u people but i kept getting diff. answers and im tired)
Usinmg the data in the table below answer the following question.
(Table)
Planet - Acc. of Gravity
Earth - 9.8ms^2
Mars - 3.7ms^2
a person stood on scales that were designed for the Earth whilst on Mars. The scale gave a reading of 50kg. What is the actual mass of the person?
A) 132.4kg
B) 50kg
C) 18.9kg
D) 490 N
(i know this is an easy question but its just im a simple person you see!)
and this one
A projectile is fired horizontally at 10ms^-1 from the top of a cliff, 55m high, into the water. What is themagnitude of its velocity as it impacts with the water?
A) 32.8ms
B)1078ms
C) 1175.8ms
D) 34.3ms
could any one please give answer and an explanation?
thx ahead

k
for the second one
i hope i'm right... here it goes
ok so ux = 10 m/s
since it is fired horizontally therefore uy =0
sy= 55 m (as given in the question)
using
v2 = u2 +2as
subbing in values
v2 = 0 + 2(9.8)55
vy = 32.8 m/s
now ux = vx
therefore vx = 10 m/s
now u need to use vectors to calculate the finla velocity
..... as for the first one i'm still thinking
ahhhh ...can someone do the vectors thingy... i really need to go continue cramming
sorry man
EDIT:
sorry all u have to do is use pythagoras
32.8 2 + 102 = v2
v = 34.3
sorry if i caused any confusion
