A duck has a mass of 2.10 kg. As the duck paddles, a force of 0.140 N acts on it in a direction due east. In addition, the current of the water exerts a force of 0.180 N in a direction of 57.0° south of east. When these forces begin to act, the velocity of the duck is 0.100 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 3.80 s while the forces are acting. (Note that the angle will be negative in the south of east direction.)

A duck has a mass of 2.10 kg. As the duck paddles, a force of 0.140 N acts on it in a direction due east. In addition, the current of the
water exerts a force of 0.180 N in a direction of 57.0° south of east. When these forces begin to act, the velocity of the duck
is 0.100 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 3.80 s while the forces are acting. (Note that the angle will be negative in the south of east direction.)
