A 10-M Plank Is Being Moved by Rolling It Over

question 65

Short Answer

A 10-m plank is being moved by rolling it over two cylindrical logs with a radius of 20 cm, placed 2 m from either end of the plank. As the plank is pushed, the logs roll on the ground without slipping, and they do not slip with respect to the plank. Through what angle will the logs have rotated when the plank has moved 2 m?
