Hey look, an update from me! its only been...um...2 weeks..
eh well anyway, today had micromouse competition, and out of the 3 sent into div 1, 2 made it into finals.(NICE 1 ALVIN, KP)
thats not bad.
as compared to open catagory, where no1 from SJI made it.
owch.
Well, and we learnt there how to make a homemade gas cannon.
We got coke, shook it abit, sideways, then aft shaking it for sometime, released abit of the cap, then spun off the cap, and..
The ceiling of the competition hall is abt 2.5 storeys high. thats around 12m.
the cap flew up and impacted in 0.5seconds.
speed = 12/0.5
= 24m/s
converted into km/h,
24 / 1000 x 60x 60
= 86.4km/h
Thats means we made the coke cap fly as fast as a car on a highway.
now that was with a 500ml bottle, what would happen with as 1.5 litre bottle?
EDIT: daryl from RI says that because of overcoming gravity and air resistance, our coke cap went wayyy faster than a car. so thanks.
tomorrow will be set path competition, we race on a path thats already given, and well...see whos the fastest.
Oh, and i changed to a new plan, so new phone, and new no.
its 91089593, please re add me. thanks.
