Question

A model airplane heads due east at 1.50 meters per second, while the wind blows due north at 0.70 meter per second. The scaled diagram below represents these vector quantities.
A)1.7m/s
B)1.7m/s^2
C)2.2m/s
D)2.2m/s²

Answer 1

The resultant physical quantity, velocity is 1.7 m/s. The correct option is A.

What is triangle law of vector addition?

When two  vectors are represented by vectors, their resultant will be the closing side of the triangle.

A model airplane heads due east at 1.50 meters per second, while the wind blows due north at 0.70 meter per second.

The right angle triangle is formed from the two velocity vectors and its resultant will be its hypotenuse.

Then, from the Pythagoras theorem,

Vr ² = (0.70)² + (1.50)²

Vr = 1.65 m/s

Thus, the resultant velocity is approximately  1.7 m/s.
