Unformatted text preview: Superimpose an x- y coordinate system on the flowing river that makes the +x direction East and +y North. Then the ferry boat’s velocity w.r.t. the river resolves along the x direction as v BRx = 12 km cos(120o ) = −6 km . But the river is flowing w.r.t. h h to the shore at vRSx = 6 km . The x component of the ferry boat’s velocity w.r.t. the h shore is vBSx = vBRx + vRSx = −6 km + 6 km = 0 . With a zero x component w.r.t. the shore h h the boat is heading entirely along +y and thus due North.
