Its easy.

What the heck is that ?
Sry i only understand english

Ignore the hindi part. Its just the translation of the question.

I ve got d ans.

For the first question?

yes

Its a. Might me some minor mistake.

Here
Suppose the block has moved a distance x

then at position x balance the forces i.e.
mgsin(-) - umgcos(-) = 0
Integrate this from 0 to x

u get the answer on simplification.

Reply when done

Well i get this sin(-)=mu*x^2/2*cos(-)
Doesnt give me the required answer? @lordcyborg

there is no m term on RHS

and u missed an 'x' term on LHS

Oh. But you cant balance forces for the body to stop right? You have to conserve the work done?

lol.........Dont go too deep...........i'm balancing forces when body is at rest

I dont think you can balance force for the body to be at rest.

ya we cannot all times.........bt we can

Why doesnt conservation of energy give me the answer?

C'mon man............I gave u the perfect(i suppose) reasons.........now go and sleep it 2:15 a.m.

Yeah you did. Thank you.

for 2nd part, limit of v will be from 0 to v, of x will be 0 to tan@/u0
^_^

:O mere dimaag me kabhi nhi aata ye,
2nd part konsa? Heat produced?

oh sorry, nahi 3rd part me ye.
heat produced me work energy lagayenge
(SHAYAD) :/

Hmm. Equation likh do 2nd part ke liye. :/

(SHAYD)
:/

check kar lena, maine bola hai to high probability hai ki galat hoga.
3 baj gaya! :O
gtg
bye

Acha ruk.. Sahi hoga. :/
Ke 0 kyun hai?
x to lamit 0 se x/2 tak nhi jayega?

1st one by 1=v*dv/dx right?

a*

I'll try solving it by work-energy theorem tomorrow, but now I have to go to bed.

Yeah i am looking for that solution. Alright. Thank You.

Right. I'll try and get back. And please see if we can do it by work energy theorem too.

sorry i flipped sin and cosine terms... so the answer should be 4 like someone said earlier.. :-/..
