2nd period was english?? think so... haizz got to be depressed over my oral marks again 29/40.
3rd period was! was?????shit cant remember.. lets see.. muz be a slack period la
4th-5th was physics.. half-life! coutner strike.. wahahha i was like asking alot of qn..like can we determine when the object start decaying? den i was thinking if the qn gif u the object finished 3 halflife den can count back right? budden if countback the difference in time would be greater to a certain extend till if u tink like me = no possible start at all.. so how can QUESTIONS exist at first??
recess---> ate sum jap food.. yucks.! :P
PE lpayed soccer.. haizz 3 teams of 5.. me zhi wei licoln cumar and j pang 1 team.. j pang keeper he damn useless man.. we lost 1-0 1-0 0-0.. i mean both goals they score j pang slping 1 he go walk out chat wif sum1 the other is siple catch den miss :?( hiazz how to depend on him??? i tink i going to play soccer wif the chess peeps tml at jace house
last block/period was history.. sum history test i nv study at all!! sturction essay on sum is the long march the main reason why the CCP survive till 1937?? den i just pluck from sky 2 other reason and wrote

i am going to end this blog entry for an a math qn to leave pple reading to think abt. its sec 4 work so those nc16 onli will know
A body moves in a straight line and its distance,s m, from a fixed point O is given by s=t^3-6t^2+9t+56, where t is the time in seconds after passing O.
d) find the total distance moved in the first 3 seconds of its motion
i spent like 5 mins arguing wif me a math teacher dat the qn phase wrong as s shld be displacement and not distance or else if s = distance den they would be more den 1 answer for d(thinking out of e box)
ok distance= positive onli, displacement = positive and negative.. so this is wad i thuogh
first to solve d u find from t=0 to t=1.. where t=0=56 and t=1=60.. ok so u get 4m correct? den from t=1 to t=1 u haf t=1=60 and t=3=56 so its 4m correct? so total distance move 8m right? budden THINK out of the box me go think abt this
<--------------------- O ---------------->--------->
(t=0,s=56)
since tat t=1,s=60m distance from O and they say that body moves in straight line why cant the body move all teh way back pass O into the left hand side to make this?
<----(t=1,s=60)---------------- O ----------------(t=0,s=66)------------(t=1,s=60)
there are two places where t can be =1!!!
so i asked my tuitor todae den he couldnt find way to rebute me.. den he said he gonig home to think.. (he sum scholar 4 distintcion 2 s paper disction JC).. tml i gonna tell my teacher and see what she thinks..
the key concept is DISTANCE cannot be negative. while displacement can! so if qn is displacent den the ans is 0.. distance den more den 1 qn
