Answer:
Resultant velocity, v = 102.95 km/h
Step-by-step explanation:
We have,
Speed of airplane due north is 90 km/h and due west is 50 km/h. It is required to find the resultant velocity of the plane. One velocity is in north direction and other in west direction. Velocity is a vector quantity. The resultant velocity of the plane is given by :
So, the resultant velocity of the plane is 102.95 km/h.
