Consider a Disc of mass M and radius R, I applied force F tangentially on it. Now using F=Ma , acceleration comes up to a=F/M
Now, let's use the torque equation: Here, the moment of inertia I is 12MR2 , and let α be the angular acceleration. Now, torque equals FR, so FR=12MR2α and, putting the rolling without slipping assumption a=αR, we get a=2F/M What gives rise to this discrepancy?
