got this from pam.. haha..

help me to do!

see the results!


yeah! spa is finally over.. n to think tt phy skill A leaked out.. entire qn la.. efficiency of a catapult.. was up till bout 1+ last nite.. discussing with yong guan wad to write for the factors/how to measure/wad to write etc.. msn is not good for discussion.. ended up toking on the phone.. haha.. then after tt i started to babble nonsense so we reverted back to msn.. actually i was supposed to sleep after we hung up.. but then continued on msn.. hahahh! tt was at 11+ 12+ i think.. then after tt thought of various methods.. in the end we din use them cos yong feng had a better one which he told us in the morn.. so yong guan n me stayed up to write the entire thing out.. i finished first so i fell asleep.. think he slept at bout 2.. cos he msged me at 1+ [by then im sleeping.. actually juz tossing arnd cos too hyper to sleep] to tell me tt temperature cannot be used.. then replied him in the morn at 650.. haha.. after tt msged until met him in skool.. both of us were like gg mad liao la.. bo bian so he went to ask his classmates.. while i hung around my class.. then *tada* along came yong feng who told us how to do.. not bad.. :D muz thank him siaz.. ok i did actually.. anw so i went to find yong guan n the two of us were like "enlightened" by yong feng's method.. haha! so yupz tts wad we used for the exp.. though it was rather confusing.. considering u calculate theoretical max ht from 1/2kx² = mgh n then efficiency is the experimental ht over the theoretical ht.. hahha!

im juz so glad this week is over.
