Final answer:
After 2 seconds, the balloon will have traveled 4 meters to the south, because the perpendicular wind blowing from the west does not affect the southward distance traveled.
Step-by-step explanation:
The question asks about the distance a balloon will travel southward given its initial southward velocity and the effect of a perpendicular wind blowing from the west. Since the wind's effect is perpendicular to the balloon's initial direction, it will not affect the southward distance traveled. Therefore, using the equation distance = velocity x time, and given that the balloon's velocity is 2 m/s south and the time given is 2 seconds, the distance traveled south can be calculated by multiplying these two values.
Distance South = 2 m/s x 2 s = 4 meters south
Thus, after 2 seconds, the balloon will have traveled 4 meters south, regardless of the wind blowing from the west.
