Question

an airplane flies at 200.00Km/hr with respect to the air. What is the velocity of the plane relative to the ground if it flies with
a. 50 km/hr tailwind?
b. 50 km/ hr headwind?
draw schematic and explain

Answer 1

a. 50 km/hr tailwind?

The wind is rushing the airplane, so it's velocity increases:

V = 200.00[km/h] + 50[km/h] = 250[km/h].

b. 50 km/ hr headwind?

The wind is retarding the airplane, so it's velocity decreases:

V = 200.00[km/h] - 50[km/h] = 150[km/h].
