Or you can do normally too

Any particular reason for taking acceleration towards kx?
@SirLancelotDuLac
You could've taken it opposite also but you would have arrived at the same result.
Just note friction is opposite to kx
Also dude ma se how did you go to to rotation ka equation
Why? Agar spring expand ho raha hoga then friction would be along kx na
torque is due to friction so just do f.R=I*alpha and you know alpha times r is acceleration of c.o.m.
Oh ha sori rotation padhe time ho gaya hai
Look very locally at point of contact, the point just above it tends to go to left, so you have to put friction to the right.
Ohhhhhhhhh to just cuz tendency hai we can take forces opposite to each other?
Ofc in such cases only
