1) 05:28 Sir said the angle is 53 degrees in the question 05:32 so accordingly answer would be Vcos53 2) 12:20 is a calculation error-- velocity will come out to be +8m/s which will be opposite to that of pulley A

[vishalsharma-bgfg]

Sir ji aj tk jivan me aisi simplified physics nhi padhi mene. Love you from bottom of heart

[shubhamraj]

Sir.. Please upload a video of wedge constraint... Hit like if u agree

[misbafayaz]

40:19 I think the ans should be 25/3 it will be v cos 53 as the angle between string and block =53

[shivangivishwakarma]

Sir I lyk the way u teach.
And literally I understand it very well. Sry to say But by mistake aapne first example m angle cos37 le liye it's actually vcos53'

[anubhavsinghal]

This is really awesome.... I must say, people like you motivate students who prefer self study instead of expensive coaching centers.... Thank You Very Much... Sir!

[chiranjeebdas]

12:30 Velocity of blockB is +8m/s as it's mathematically right and sign conventionally...

[PhysicsExpressCMSir]

Everyone is copying your contents, and getting more famous...but you are India's best sir...

[kvbnmkkm]

Thanks for this help sir,
A lot of students who can't afford expensive coaching are getting benefitted by this initiative of yours.
May the DIVINE POWER bless you with even more knowledge, health and wealth....

[techstreax]

sir at 12:52 i think that the answer should be positive 8ms instead of negative become b will movw upward

[robinguglani]

no matter about mistakes but concept clear ho gya sir thanks alot sir thanks a lot ..

[rajkumargupta]

Thank you very much sir!
It was easily understandable and many illustrative examples helped me alot.

[aacharyahemantmudaliar]

First example me angle 53 tha aapne calculation ke time 37 liya hai

Velocity of B +8m/s aayega aapne -8m/s le liya hai

[imranshaikh]

Dot product method is far easy that sir's method but sir increased clarity of my concept

[onamission__]

Sir apse pdne ka sapna sapna hi reh gya

[nmpai]

sir first eg :_ v cos 37 is not equal to 5..plss check..consider v as 5 and v cos 37 as vb...then vb=5*4/5 =4

[marihaferoz]

gud video it clears all concepts related to constraint equation

[aryasg]

Thanks a lot sir duniya bhar se padha lekin apke jitna conceptual clarity aur kahin nahin mili sir

[dbdoxbxb]

Sir saare question khud karpaya thanks sir vaise first question me aapne cos53° ko cos37° le liya hai

[SumiSeby]

Sir, at 5:34 isn't the angle that you took 53, in the question?
