Question: A 307-kg boat is sailing 13.8° north of east at a speed of 2.16 m/s. Thirty seconds later; it is sailing 32.4° north of east at a speed of 3.76 m/s. During this time, three forces act on the boat: a 28.8-N force directed 13.8° north of east (due to an auxiliary engine), a 25.3-N force directed 13.8° south of west (resistance due to the water), and vector F W (due to the wind).
Part I: Find the magnitude and direction of the force vector F W.
I need help to solve the above question and express the direction as an angle with respect to due east.
