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: ->->->->->->->->->->->-> :

Since the direction of the gust of wind is opposite the direction of motion, and the net force is now in the direction of the gust, then I would assume that the airplane slows 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: ->->->->->->->->->->->-> :

I'm not sure if it would veer to the left or to the right. It sounds as if the direction of the gust is in the exact opposite direction of motion ( south east vs north west). Also, the force of the wind is strong enough to completely change the net force to south east. I think the direction of veering would depend on the plane's original angle above the horizontal.
