A plane has an airspeed of 142 m/s. A 30.0 m/s wind is blowing southward at the same time as the plane is flying. What must be the heading of the plane in order to move directly eastward relative to the ground?

Respuesta :

Answer:

[tex]\theta=12.19^{\circ}[/tex]

Explanation:

Given that

The speed of the airplane ,v= 142 m/s

The speed of the air ,u = 30 m/s

Lets take angle make by airplane from east direction towards north direction is θ .

Now by using diagram ,we can say that

[tex]sin\theta =\dfrac{u}{v}[/tex]

Now by putting the values in the above equation we get

[tex]sin\theta =\dfrac{30}{142}[/tex]

[tex]sin\theta=0.21[/tex]

[tex]\theta=12.19^{\circ}[/tex]

Therefore the angle will be 12.19° .
