Question

A. v=⟨220,−90,10⟩ km/h
B. v=⟨220,−90,20⟩ km/h
C. v=⟨200,−90,10⟩ km/h
D. v=⟨220,−100,10⟩ km/h

Answer 1

In physics, when a plane flies at 200 m/s north and faces a headwind of 70 m/s, the resultant velocity would be 130 m/s north.

Step-by-step explanation:

The subject in question is Physics, specifically dealing with the topic of velocity and the effects of wind on an airplane's path. When a plane flies north at a velocity of 200 m/s against a headwind blowing from the north at 70 m/s, the resultant velocity of the plane would be the velocity of the plane minus the velocity of the wind. Hence, the resultant velocity of the plane is 200 m/s - 70 m/s = 130 m/s due north.

The resultant velocity of the plane can be calculated by adding the velocity of the plane to the velocity of the wind. In this case, the velocity of the plane is given as v=⟨220,−90,10⟩ km/h. To find the resultant velocity, we need to add the wind velocity to the plane's velocity.

Since the wind is blowing, it will affect the plane's velocity. However, the question does not provide information about the wind's speed and direction. Therefore, we cannot determine the resultant velocity of the plane.
