due east.
b After flying 5 km from A to B. the aircraft returns along the same
path from B to A with a resultant velocity of 13.5ms-. Assuming
that the time spent at B is negligible, calculate the average speed for
the complete journey from A to B and back to A.

Suppose a pilot flies 40.0 km in a direction 60 north of east and then flies 30.0 km in a direction 15 north of east as shown in Figure 3.61. Find her total distance R from the starting point and the direction 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.
