Question:
The 20-kg roll of paper has a radius of gyration kA = 120 mm about an axis passing through point A. It is pin supported at both ends by two brackets AB. The roll rests on the floor, for which the coefficient of kinetic friction is μk = 0.2. If a horizontal force F = 60 N is applied to the end of the paper, determine the initial angular acceleration of the roll as the paper unrolls.

My experience has a tutor has helped me with learning and relearning. You learn everyday actually and there are changes that are made to the curriculum every time so being a tutor has helped in keeping me updated about the present curriculum and all.
I have also been able to help over 100 students achieve better grades particularly in the categories of Math and Biology both in their internal examinations and external examinations.
