Why aren't we taking the translational kinetic energy into account?
I mean the center of mass will also have a translational velocity.

+solved @user to close the thread when your doubt is solved. Mention the user who helped you solve the doubt. This will be added to their stats.Maine toh isko Torque = I * alpha
se kiya
answer aa gya, but energy method mei translational KE kyon nhi le rhe
Bhai rotational hi to Li h solution me
Bhai mera qs toh padh -_-
mai keh rha
mechanical energy conservation mei translational kinetic energy kyon nhi li hai
they've taken moment of inertia about point of rotation, and KE of that point is 0.
if you were to use translational KE of COM, you'd be calculating rotational KE about COM as well, and that happens to give the correct answer as well (i checked)
wait what
I didn't know this shit cuz generally we take axis around center of mass
thanks
something to learn everyday
