But won't dm = lambda dx / 2 , so if we use the former argument, we will get the official answer , and how is internal force assisting F which appeared due to F , it's kind of hard to wrap my head around it

This example makes stuff pretty clear

Ooh like tension ?

How is Fdm result of accelerating mass ? Isn't it a internal force which bounds the wire ?

Alright i will work on it , it might take me some time but i will reply when i am done

Honestly i am having trouble keeping up with this stuff , i am not used to this level but this is the second question in this section ( we have sections based on difficulty) so sorry if it comes off like i have no clue

Could you explain this part i more detail i can't understand it

Damn , i thought something similar to your first explanation but never about this in such depth . Thanks for the detailed explain:) . I will dicuss option 4 with my sir and get back to you tomorrow thanks a lot .

I read the same solution somewhere else but couldn't understand why we took average

Why average though

Well i know the reasoning is bad but i guess we can ignore rotational mechanics here as this question is before that was even taught . And i checked the solution and they wrote v as equal to vo/2 [dx/dt = v , this v ] As for the conservation of work i will try solving through it , i got a test...

Done

Oh my bad i forgot to upload the figure

So i got some equations but i think i am missing something, my main doubt is what is the relation between dx / dt and v(o) [ here] . Workings in attachment
