A 373-kg boat is sailing 12.0° north of east at a speed of 2.00 m/s. 31.0 s later, it is sailing 39.0° north of east at a speed of 4.00 m/s. During this time, three forces act on the boat: a 31.9-N force directed 12.0° north of east (due to an auxiliary engine), a 20.8-N force directed 12.0° south of west (resistance due to the water), and (due to the wind). Find the (a) the magnitude and (b) direction of...
