CQ_1_22.1_labelMessages.txt

An airplane traveling to the northwest is exerting just enough force to overcome wind resistance. It encounters a sudden wind gust which is directed at 30 degrees south of east, which results in a net force in that direction.

• During the half-second before the pilot has time to react to the gust, does the airplane speed up, slow down or maintain constant (or very nearly-constant) speed?

answer/question/discussion: ->->->->->->->->->->->-> :

The airplane would slow down because southeast is the complete opposite of northwest, which means the wind is acting straight against the airplane.

@&
The wind is to the south, not the southeast, so it isn't directly opposite to the plane's direction of motion.

However the component of the gust's direction along the line of motion is counter to the motion of the plane, so it would indeed slow down.

• Does it veer a bit to the right, a bit to the left or does it continue traveling along a straight line?

answer/question/discussion: ->->->->->->->->->->->-> :

Since NW is 45 degrees in the second quadrant and the wind is coming from SE at 30 degrees, the wind will push the plane from the left making it veer to the right a little.
