mihir: a goongi cat can't walk
kyun?
coz the cat is goongi,
toh mew mew ni kr sakti.
Is liye mew (coeff. of friction) is zero.
so cat can't walk...
;-)
rohit: i'll tell you how the cat can walk, ask the cat to spit with as high velocity as it can.
the spit has mass and veloc.
so the spit has momentum. as there is no force acting along x-axis, not even friction (read: mew = 0) therefore, momentum is conserved along x-axis. So velocity of cat remainsconstant along x axis.
to increase speed, spit in same direction.
to stop, spit in oppositedirection.
to move left/ right or perform a 2-dimensional motion spit at a particular angle.
hence,the cat can walk.
GAME OVER MIHIR!
vj: hey rohit,dat wnt make d cat walk,on d contrary it wud make it slide...
& anothr point dat shud b noted is dat d spit hs negligibe mass,so no momentum as such!
rohit: once it starts moving, it can move its 4 legs pretending 2 walk.
they wont help it in moving but it will fool people like you who'll think it is WALKING!
vj: it'll nt pretend cuz dat wud bruise its legs!
& evn if it did,dat wnt fool me cuz i noe dat its dumb(i.e. mew=0)
& wat abt d mass of th spit being negligible?
rohit: my dear friend, it wont bruise its legs coz you know mew=0 so no friction- no heat loss-no bruises.
you probably know how spacecrafts are launched with the help of air.
agreed,mass of spit is very less compared 2 that of gases but so is the mass of cat compared 2 that of spacecrafts.
also,cat is not going against gravity unlike the spacecrafts.
nor does it want 2 move at the speed of space crafts.
some good amount of spit at one time and move for time-immemorial for high speeds,it can sometimes do no:1 and no:2 in as straight direction as possible.
both have mass and have some component along x axis as well.
varun,are u done now?
vj: ultimate counter:
cats do not spit!
:-p
now, are YOU done, rohit?
or do you have anything else to say?
;-)
tch... tch... tch...
rohit: all mammals do spit.
check your bio book class 8th.
if you didnt study in 8th,its not my fault.
and you've forgotten i've given you another option.
now get lost!
vj: hahaha!
all mammals spit!
hadd h yaar teri bhi!
u,bettr check ur 8th bio book!
& btw i didnt gt ur othr option,ws it movement wid th help f certain 'gases'?
rohit: atleast cats do i'm sure of that.
other option was of doing no:1 and 2
vj: spitting means deliberately forcing saliva out f ur mouth & only humans can do dat!
all mammals produce saliva bt they cant spit!
& othr options,well how r u supposed to shit and pee wen there's no friction (i.e. no coefficient f friction)!
i mean ki even body-organs require friction fr excretion!
:-p
rohit finally calls, the recorded conversation is here:

enjoy!
