okask suchal I am too asking him
then please ask and tell
He will quote you dwthen please ask and tell
lol, I didn't read the question. I'am silly.It asked when it reached half the height
Neither did Ilol, I didn't read the question. I'am silly.
dw?He will quote you dw
then how did u know ?Neither did I
Don't worry
okDon't worry
It came In my mid term exams i did it wrongthen how did u know ?
Woops! so you got its solution Any doubts ?It came In my mid term exams i did it wrong
please can you tell why should divide the height by 2 for the 10th question in paper 1 may june 2012 variant 13 regarding the man and the barrel? thanksIt was a doubt wasn't it?
the only time the man head will level with the bottom of the barrel will be in the middle if the man goes 10 meters up the barrel will not level it be below his headplease can you tell why should divide the height by 2 for the 10th question in paper 1 may june 2012 variant 13 regarding the man and the barrel? thanks
Genius...the only time the man head will level with the bottom of the barrel will be in the middle if the man goes 10 meters up the barrel will not level it be below his head
i hope you get the point here
Sarcasm?Genius...

yes thank youthe only time the man head will level with the bottom of the barrel will be in the middle if the man goes 10 meters up the barrel will not level it be below his head
i hope you get the point here
I feel honoredwe'll take this problem in terms of the forces acting on the barrel and the man
for the barrel: the force due to the barrel - the tension in the rope(T) = ma (because the barrel move's down, the force due to the barrel is greater than the tension)
(120*10) - T = 120a (we dont know the acceleration of the man and the barrel)
for the man: the tension (T) - the force due to the man = ma
T - (80*a) = 80a
find the value of a using simultaneous equations, which is 2 ms^-2
using v^2=u^2 + 2as
find the final velocity of the man at 9 m, taking u as 0 ms^-1
