a duck has a mass of 2.5 kg. as the duck paddles, a force of 0.10 n acts on it in a direction due east. in addition, the current of the water exerts a force of 0.20 n in a direction of 52° south of east. when these forces begin to act, the velocity of the duck is 0.11 m/s in a direction due east. find the magnitude and direction (relative to due east) of the displacement that the duck undergoes in 3.0 s while the forces are acting.
