Diablo:
How did you guys get the 1/8 fraction?

Step by step please?

Wasn't it the second answer over the first answer (54000?)

MR.BooMBastiC:
ok 1 st ans was 540000 J!!

agreed!!

MR.BooMBastiC:
now 4 the 2nd question!!!

the said 10% of ke...
so...10/100x540000=54000J

OK!!!!!!!!

NOW POWER=WORKDONE/TIME TAKEN

SO WORKDONE=KE

HENCE 54000/1
CUZ TIME WAS 1 SECOND!!!!!!

SO ANS=54000W OK

cherrip:
they accept efficiency rule too  instead of power= energy\time ??? ??
for th fraction part , i calculated kinetic energy for half h wind speed and calculated output energy by muliplying by 10%
second answer\first one = 0.125 which is 1\8...
what fractions dd u get??

MR.BooMBastiC:
i git 1/8 wat abt u
