A 315-g model boat floats on a pond the wind on its sail, Ask an Expert

Academics

A 315-g model boat floats on a pond. The wind on its sail provides a force of 1.6 N that points 20° north of east. The drag force of the water on the boat is 0.65 N, toward the west. If the boat starts from rest and heads east for a distance of 2.7 m, how fast is it moving?
