27. A cruise ship is sailing north at a speed of 10 km/h. A passenger walks along the deck
with a velocity of 0.5 m/s toward the stern of
the ship. She then turns toward port and walks
to the railing at the same speed. Determine the
passenger's velocity for both motions
a) relative to the ship.
b) relative to the water.
