11 The pilot directs the aircraft to fly due north at 600km/h. A side-wind blows at
100km/h towards the east. What will be the aircraft's resultant velocity? (Give both its
speed and direction)

Explanation:

Given that,

The pilot directs the aircraft to fly due north at 600km/h.

A side-wind blows at  100km/h towards the east.

We need to find the aircraft's resultant velocity. et it be v. It can be calculated as follows :

For direction,

So, the aircraft's resultant velocity is 608.27 km/h and it is at and angle of 80.53°.
