1. An Olympic canoeist, capable of traveling at a speed of 4.5 m/s in still water, is crossing a river that is flowing with a velocity of 3.2 m/s [E]. The river is 2.2x10² m wide.
   1. If the canoe is aimed northward, as shown in the figure, what is its velocity relative to the shore?
   2. How long does the crossing take?
   3. Where is the landing position of the canoe relative to its starting position?
