An airplane is heading due east. The airspeed indicator shows that the plane is moving at a speed of 370 km/h relative to the air. If the wind is blowing from the north at 92.5 km/h, the velocity of the airplane relative to the ground is?

Respuesta :

Answer:

Vp = 358.3m/s

Explanation:

Taking

North: UP

South: DOWN

East: RIGHT

West: LEFT

In the attachment, the velocity vector triangle is shown for the scenario. the triangle formed is a right angled triangle.

We can apply the Pythagora's Theorem.

370 ^ 2 = 92.5^2 + Vp^2    (Vp: plane velocity relative to ground)

Vp = sqr.rt(370^2 - 92.5^2)

Vp = 358.3m/s
