Aduck has a mass of 2.70 kg. as the duck paddles, a force of 0.130 n acts on it in a direction due east. in addition, the current of the water exerts a force of 0.160 n in a direction of 56.0° south of east. when these forces begin to act, the velocity of the duck is 0.120 m/s in a direction due east. find (a) the magnitude and (b) the direction (relative to due east) of the displacement that the duck undergoes in 3.20 s while the forces are acting. (note that the angle will be negative in the south of east direction.)
