A baby elephant is stuck in a mud hole. To help pull it
Chapter , Problem 48(choose chapter or problem)
A baby elephant is stuck in a mud hole. To help pull it out, game keepers use a rope to apply a force FA B , as part a of the drawing shows. By itself, however, force FA B is insuffi cient. Therefore, two additional forces FB B and FC B 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 5 2.00.
