1. The figure below shows a plank leaning against a wall. The plank has a mass of 20.0 kg distributed uniformly along its 10.0 m length. The wall is smooth but the floor is rough, and the coefficient of static friction between the plank and the floor is 0.300. An externally applied force F is parallel to the floor and applied 2.00 m from the bottom of the plank. Determine the minimum value of the magnitude of such that the plank will just start to move toward the wall. 2.00 m 8.00 m
