Thin uniform rod AB of mass m =1.0 kg moves translationally with
acceleration w = 2.0 m/s2 due to two antiparallel forces Fx
and F2
(Fig. 1.52). The distance between the points at which these forces are applied
is equal to a = 20 cm. Besides, it is known that F2 = 5.0 N. Find the length of the rod.
