Thank you, was having a spot of bother with a similar question, cleared up now :)

[samarpratapsingh]

Excellent knowledge liberating over here. Really superb!!!

[devin]

very good video's thanks a lot <3
but this time you went to quick at 5:13, how is it related to the time with Vcm = root(2sa)?

[bostangpalaguna]

well, in the case of "rolling without slipping", we can elaborate further the I = kmr^2, right? so we got easier formula V=sqrt(2gh/(k+1))

[ytboy]

The torque explanation was exactly what I needed

[arindammandal]

Work energy theorem would come handy here

[crystal_royal]

Is there an faster algorithm to solve this problem

[navkhr]

torque due to friction should be in - k direction?

[NicolaeComan]

Why τ_cm=f_s⋅R and not τ_cm=m⋅a_x⋅R?

[dhirajmahajan]

Sir how you find axis of rotation by
?

[congsontran]

what if the object was box would friction force cause it rotate ?

[emmanueldavid]

it looks like he's writing backwards lol
