A 379-kg boat is sailing 11.0° north of east at a speed of 1.80 m/s. 35.0 s later, it is sailing 38.0° north of east at a speed of 4.30 m/s. During this time, three forces act on the boat: a 32.1-N force directed 11.0° north of east (due to an auxiliary engine), a 21.8-N force directed 11.0° south of west (resistance due to the water), and (due to the wind). Find the (a) the magnitude and (b) direction of...
