Question: 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 2.3 m/s in a direction 31 degrees east of north relative to the Earth. It encounters a wind that has a velocity of 4.1 m/s in a direction of 53 degrees south of west relative to the Earth. What is the magnitude of the velocity of the wind relative to the water in m/s? What is the angle of the velocity of the wind relative to the water degrees S of W?
