Question
A person carries a plank of wood 2.00 m long with one hand pushing it down at one end with a force F, and the other
hand holding it up with a force F, at a distance of 0.500 m from the same end of the plank. If the plank has mass 20.0 kg
and the center of mass of the plank is in the middle of the plank, what are the magnitudes of the forces F and F,?
F, = 196.2 N, E, = 392.4 N
