Drag Force on a Barge

(a) A view from above of two tugboats pushing on a barge. (b) The free-body diagram for the ship contains only forces acting in the plane of the water. It omits the two vertical forces—the weight of the barge and the buoyant force of the water supporting it cancel and are not shown. Since the applied forces are perpendicular, the $x$- and $y$-axes are in the same direction as $F_x$ and $F_y$. The problem quickly becomes a one-dimensional problem along the direction of $F_{\text{app}}$, since friction is in the direction opposite to $F_{\text{app}}$.
