A 327-kg boat is sailing 18.0° north of east at a speed of 2.30 m/s. 21.0 s later, it is sailing 32.0° north of east at a speed of 4.20 m/s.
During this time, three forces act on the boat: a 32.1-N force directed 18.0° north of east (due to an auxiliary engine), a 24.6-N force
directed 18.0° south of west (resistance due to the water), and F (due to the wind). Find the (a) the magnitude and (b) direction of the
