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:
It speeds up but in the direction of the southeast which is reverse of the direction it is traveling.
The way I understand the scenario is that the plane is exerting force against the wind but only barely enough to travel a little forward. When the gust
comes, the force of the wind is greater than the force the plane is exerting and it travels backwards.
However, if the plane is traveling at a high rate of speed, the wind gust would just slow down the plane not make it go in reverse.
A net force results in an acceleration; it takes the acceleration time to change the velocity.
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:
Traveling along a straight line
It is traveling northwest and the gust goes directly against it to the southeast.. Not just to the N, S, E, W.
The gust isn't directly opposite the direction of motion.
