Homework Help: physics

Posted by John on Sunday, November 25, 2012 at 2:27pm.

A duck 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 0.210 N in a direction of 52.0 south of east. When these forces begin to act, the velocity of the duck is 0.110 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 2.70 s while the forces are acting. (Note that the angle will be negative in the south of east direction.)
