hey the final answer is 1440J ... if it is right,then tell me ....I will post the answer with steps........If you don't know the answer.......you have to give me permission to post my answer.....
yes you can post the ans
sorry the answer is 30J
yes you are right .The answer is 30J.I also calculated the equation now.And thanks for giving the answer
hey why did you reported my answer .....I said sorry na.....I said I will edit my answer.....why?????
so what am i saying you now
I could have edited my answer if you didn't report my answer...

what is true ans
60J....
ok hmm
so finally ans is 60J
yes
only his mistake was under root 24
only his mistake was under root 24
yes use 2root6 in the final equation of mine.....you will get 60J....
only his mistake was under root 24

work done = mass ×acceleration×distance
force=m×a
mass=5kg
F=10N
10 = 5×a
a =2 m/s^2
K.E=5×2×6
=60 J
force=m×a
mass=5kg
F=10N
10 = 5×a
a =2 m/s^2
K.E=5×2×6
=60 J
60 j
ok
30J is correct
uder root 24 =
2under root 6 should be there check his
2 under root 3 should be there
better to check yourself once again...
gayatri......did you report my answer
no
ok !!! who knows.... I am leaving.......sorry to every one....
