A barge is pulled by the two tugboats shown in the figure below. One tugboat pulls on the barge with a force of magnitude 4000 units of force at $15^{?}$ above the line $AB$ (see the figure) and the other tugboat pulls on the barge with a force of magnitude 5000 units of force at $12^{?}$ below the line $\mathrm{AB}$. Resolve the pulling forres to their sralar comnonents and find the comnonents of the resultant force pulling on the barge. 1 , the line $AB$ ? $R=$ units of force
