You are riding in a boat whose speed relative to the water
is 6.7 m/s. The boat points at some angle upstream on a
river flowing at 1.4 m/s. The dock on the opposite shore
of the river is at the location r = 55m and y = 28m
relative to the starting point of the boat.
(Figure 1)
At what angle relative to the r axis must the boat be pointed in order to reach the other dock?
