In an attempt to escape his island, Gilligan builds a raft
and sets to sea. The wind shifts a great deal during the day,
and he is blown along the following straight lines: 2.50 km
45.0º north of west; then 4.70 km 60.0º south of east;
then 1.30 km 25.0º south of west; then 5.10 km straight
east; then 1.70 km 5.00º east of north; then 7.20 km
55.0º south of west; and finally 2.80 km 10.0º north of
east. What is his final position relative to the island?
24. Suppose a pilot flies 40.0 km in a direction 60º north of
east and then flies 30.0 km in a direction 15º north of east .Find her total distance R from the
starting point and the direction θ of the straight-line path to
the final position. Discuss qualitatively how this flight would be
altered by a wind from the north and how the effect of the wind would depend on both wind speed and the speed of the
plane relative to the air mass
