A ship sets sail from Rotterdam, The Netherlands, heading due north at 8.5m/s relative to the water. The local ocean current is 1.50 m/s in a direction 40.0A??o north of east.
Part (a) In what direction would the ship have to travel in order to have a velocity straight north relative to the Earth, assuming its speed relative to the water remains 8.5m/s in degrees W of N?
Part (b) What would its speed be relative to the Earth in m/s?
