10. Analyzing a common mistake. Question: The still water velocity of a rower is 5 m/s. At what angle must this
rower point upstream to be able to land directly across the river? The current is moving at 3 m/s.
a. The most common incorrect answer for this type of question is 31° (from a line perpendicular to the shore).
Show a fully labelled vector diagram that illustrates how this answer was achieved. Circle the mistake and
briefly discuss the incorrect assumption that led to this solution.
