A 325-kg boat is sailing 15.0 north of east at a speed of 2.00 m/s. Thirty seconds later, it is sailing 35.0 north of east at a speed of 4.00 m/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 (due to the wind). Find the magnitude and direction of the force . Express the direction as an angle with respect to due east.
