A jet plane flies at a velocity of 200 m/s, east in still air. a) If it flies into a 20 m/s wind heading west, what is its velocity relative to the ground? b) If it flies into a 20 m/s wind heading east, what is its velocity relative to the ground?

Explanation:

a) If it flies into a 20 m/s wind heading west

The wind blows against the velocity of plane

resultant velocity = 200 - 20 = 180 m /s

velocity relative to ground = 180 m /s

b ) If it flies into a 20 m/s wind heading east,

wind will support the velocity of plane

resultant velocity = 200 + 20 = 220 m /s .

velocity relative to ground  = 220  m /s .

so mas o menos

Explanation:

a) If it flies into a 20 m/s wind heading west

The wind blows against the velocity of plane

resultant velocity = 200 - 20 = 180 m /s

velocity relative to ground = 180 m /s

b ) If it flies into a 20 m/s wind heading east,

wind will support the velocity of plane

resultant velocity = 200 + 20 = 220 m /s .

velocity relative to ground  = 220  m /s .
