PROBLEM:1.234


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.
