An airplane flies due north at 100 m/s through a 30 m/s cross wind blowing from the east to the west. determine the resultant velocity of the airplane.

The resultant velocity of the airplane is 104.4 m/s.

Explanation:

It is given that,

Velocity of airplane, (due north)

Velocity of wind, (east to the west)

We need to find the resultant velocity of the airplane. The resultant velocity is given by :

v = 104.4 m/s

So, the resultant velocity of the airplane is 104.4 m/s. Hence, this is the required solution.
