You are standing on the top deck of a cruise ship. The GPS on your phone tells you that you are moving at 16.0 m/s, 70.0° E of S. You take out a wind measuring device and you measure that the wind is blowing at 15.1 m/s, 10.0° N of W. a) How fast would a person on a nearby island measure the velocity of the wind to be? b) If you also see a bird flying backwards at 2.00 m/s, 20.0° N of W (because it is slower than the cruise ship), how fast is the bird moving relative to the air?
