A small weather balloon of weight 3.5 N3.5\text{ N}3.5 N is falling vertically through the air at terminal velocity. A sudden gust of wind exerts a horizontal force of 1.2 N1.2\text{ N}1.2 N on the balloon to the east. What is the magnitude and direction of the resultant force acting on the balloon while the wind is blowing?
