A 343-kg boat is sailing 17.0 ° north of east at a speed of 2.20 m/s. 33.0 s later, it is sailing 33.0 ° north of east at a speed of 4.20 m/s. During this time, three forces act on the boat: a 33.3-N force directed 17.0 ° north of east (due to an auxiliary engine), a 20.3-N force directed 17.0 ° south of west (resistance due to the water), and (due to the wind). Find the (a) the magnitude and (b) direction of the force . Express the direction as an angle with respect to due east.
