A 325-kg boat is sailing 15.0؛ north of east at a speed of 2.00m/s. thirty seconds later, it is sailing 35.0؛ north of east at a speed of 4.00m/s. during this time, three forces act on the boat: a 31.0-N force directed 15.0؛north of east ( due to an auxiliary engine) a 23.0-N force directed 15.0؛ south of west (resistance due to the water), and Fw (due to the wind). Find the magnitude and direction of the force Fw. Express the direction as an angle with respect to due east.
