Satu petang di dlm bas uitm

(amekla pengajaran)
aritu naek bas uitm nk balek kolej akasia
suddenly adela student yg dok sebok ckp psl toefl la ape la.. mcm nk bg 1 bas dgr.. mmg saket jiwe.. tp yg pling best dak pmpuan uh menjerit2 cam hape je.. rse nk sepak pun ade.. tp ak tutup muke ngan notes chemy..sbb glak abis2an

hawe duk sblh ak mse tuh.. dier plak.. bce buku chemy camni..
"in soil, there are insoluble compounds of hydrogenphosphate ions and ORTHOPHOSPHATE IONS!!!!!"

punye saket jiwe awe tyme tuh... haha

konklusi.. mmg btul ape yg Mdm Gouri ckp psl 'how Malaysians talk'
bertimbang rasalah

p/s: klu dh ckp psl toefl tuh,, mmg sah la bdk ****

no answer scheme.. really need help on how to approach (& solve) these questions

(ok.. mostly, mungkin ak x igt ape yg ak penah blaja tyme high school dlu.. tp, ni kwn ak dh tanye senior nk final tp mrk2 pn xpat.. mungkin lupe jugak.. spe2 yg tere.. silekn dgn sgl hormatnye)


2 blocks tied together by a horizontal string being pulled across the table by a horizontal force of 22N as shown in figure below. The 2kg block has a 6N frictional force exerted on it by the table, and the 4 kg block has an 8N frictional force acting on it. (g=9.8)
a) Determine the net force acting on the entire two-block system (4 marks)

b) Find the acceleration and the tension in the string connecting this two blocks (consider only the forces acting on this block) (8 marks)

c) If the table is frictionless, determine the acceleration of this new system. (4 marks)

*************************************

A crate of mass 45kg initially at rest, slides down at 30 degrees incline of a rough surface. The crate's acceleration is 2.2 ms^-2 and the incline is 12 m long.

a) find the kinetic energy of the crate as it reaches the bottom of the incline. (4 marks)

m=45kg , a=2.2 ms^-2 , s=12m , u=0

s=ut+ 1/2 at²

12=1/2 (2.2)t²

t=3.3s

v = u+at

v=2.2 (3.3)

v= 7.26m/s

so, KE= ½ mv²
KE= ½(45)(7.26)²
KE= 1185.921 J

b) Find the work spent in overcoming friction (4 marks)

c) Determine the magnitude of the frictional force that acts on the crate as it slides down the incline. (4 marks)

d) Determine the coefficient of kinetic friction between the crate and the incline. (4 marks)
yg ni ok je k0t klu dpt jwpn c) juz f=μN where N=mg cos ө

sesi luahan/ muntahan~

bangun tdo - siap2 pi intec ._.

9.10-11.10 pg
math studies final exam

habis exam..

jalan (approx.) 10 langkah ke blkg nk kuar dwn..

nabihah pegang tangan ak..
"aisyah, nk nangis leh x???"
*aku senyum*
-borak sket & bincang soalan-

di luar dewan..

aku jumpe hawa..
"weh aisyah, klu ak lulus exam nih, kerat jari aku.."
"abehtu klu ko lulus, nk aku kerat jari ko??"
-borak2 jap-
(syira dtg.. bincang psl soklan td)
syira to madi: "weh, ak nk stay intec, klu ak balek bilek, nnti ak tdo bunoh diri.."

dlm klas awe
(plan nak studi chemy tp ak rse cam ak babysit awe nk tdo je (sbb saket pale).. haha - xpe2 ade blaja sket)
"ak rse an, markah aku suku dr markah ko"
"weh, gle hiperbola.. klu ak dpt 100, ko baru dpt 25..tu pon klu dpt 100-impossible"

****************************
begitulahh
*sigh*

13 soalan (29 pages including cover).. 2 jam + 10 mins. reading time
(reading time yg ak pn x pasti ape tujuannyer - tp ak cube nk gne time ni utk soalan yg ak rse nk simpan last minit - tp td nmpaknyer x menjadi - test 2 haritu menjadi la sbb dpt siap sumer soalan)

dan begitulah hakikatnyer math studies.. blaja senang.. soalan menggile (boleh je nk piker tp time constraint yg teramat) - smpe 1 mse td, ak rse malas nk jawab soalan, xde smgt.. hadoi~

btw, ak dh pun accidentally 'tdo bunoh diri' selame approx. 3 jam++
so..
don't ever be carried away - chemistry luse!

PS: A cam dah terbang melayang dh (A=83%++).. mungkin B..
ak mengharap sgt2 dpt B..
x kesala, terrbaikk sudah
~pening sudah~

PPS: ak plek ngape izrin x post lpas math exam.. haha
