3) A river is 40. meters wide and its current flows southward at 4.5 meters per second. A boat is launched with a velocity of 3.0 meters per second eastward from the west bank of the river. Determine the magnitude of the boat's resultant velocity as it crosses the river. [You must draw the diagram first by using the Head - Tail method, but it need not be to scale].

While scavenging for acorns before the big winter, Scrat the Squirrel leaves his tree house and skitters along 8.00 m at a heading of 40.0° SoE to collect two acorns. Then, he traipses off 10.0 m West to snag another acorn. Finally, he sees a big prize and hurriedly rushes 12.0 m at 20.0° EoN.
