A duck has a mass of 2.0 kg. As the duck paddles, a force of 0.12 N acts on it in a direction due east. In addition, the current of the water exerts a force of 0.24 N in a direction of 47° south of east. When these forces begin to act, the velocity of the duck is 0.09 m/s in a direction due east. Find the magnitude and direction (relative to due east) of the displacement that the duck undergoes in 3.1 s while the forces are acting.
