Question

A river has a current that is flowing due east at 0.90 m/s [East]. A swimmer is
capable of swimming at a rate of 1.47 m/s in still water. The swimmer points herself
such that she swims directly across the river. What is the magnitude of swimmer's
velocity relative to shore? Give your answer in m/s to 2 decimal places but do NOT
include the units in your answer.

The velocity of the wind relative to the water is crucial to sailboats. Suppose a sailboat is in an ocean current that has a velocity of 2.1 m/s in a direction 27° east of north relative to the Earth. It encounters a wind that has a velocity of 4.4 m/s in a direction of 49° south of west relative to the Earth. 1. What is the magnitude of the velocity of the wind relative to the water, in meters per second? 2. What is the angle of the velocity of the wind relative to the water degrees south of west?
