Ababy elephant is stuck in a mud hole. to pull it out, game keepers use a rope to apply a force f with arrowa, as part a of the drawing shows. by itself, however, force f with arrowa is insufficient. therefore, two additional forces f with arrowb and f with arrowc are applied, as in part b of the drawing. each of these additional forces has the same magnitude f. the magnitude of the resultant force acting on the elephant in part b of the drawing is k times larger than that in part a. find the ratio f fa when k = 2.10. (take θ = 18.0°.) f fa = 1.05 incorrect: your answer is incorrect.
