If you would observe only the circumference of the small disc by visualise it to be rolling then it rolls 2pie*a on the circle of radius 5a fully in one roll, I think the center moves by a distance smaller than 2pie*a

As i don't know difference between solar day and sidereal day, could you please tell me what's the issue in another way,

center has smaller speed than tangential point , are you refferring to the the speed of the points on the rigid body barring rotation??, if yes then we were told in class that property of rigid body is that all points of a rigid body when considering translational motion have the same speed...

why does it get slower, it is both non intuitive and unlogical, could you explain why

what is small r that you mentioned , seeing your method I came upon another reasoning that as @ tends to 0, then w1 tends to 0 , this discredits the first approach as w1=w/lcos@ according to the first approach

L is the distance OC=root(24)*a As for the approach you mentioned you mentioned, I have also written that as my second approach I couldn't understand why the the first one is incorrect

then how much does it roll by when it rotates through 2pie*a

I assumed the angular velocity of the center of mass of the two discs about z axis to be w1 note that angular velocity of center of mass of both discs and center of anyone disc about z axis is same, you can verify that if you want, me after verifying it will use it to decrease the length of the...

then also we cannot add them and write X=1+1.05, it would be X=(1/a )+ 1.05

why are we adding these terms when a is a infinitesimal quantity

I am getting 1.05 with only second term included, neglecting the first term

i drew the diagram with BC horizontal component of the center of mass of the whole system in the same vertical line as the point where it is rest upon on the table, I am getting the answer same as given with a cot(alpha) instead of cos(alpha)

hmm, thanks for helping

but they have clearly mentioned that the whole process is adiabatic??

but the exam is such you can challenge a particular question for bonus if its a typo or its answer given is wrong, many challenged the answer as 2.05 but finally ans was not changed, it remained 2.05 I have a solution available on the internet that is doubtful to me and i have attached that...
