Answer:
Resultant velocity, v = 102.95 km/h
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 :
[tex]v=\sqrt{v_1^2+v_2^2} \\\\v=\sqrt{90^2+50^2} \\\\v=102.95\ km/h[/tex]
So, the resultant velocity of the plane is 102.95 km/h.
