A 3 30 kg boats sailing 10 Oe north of east at a speed of 1.60 m s. 31 0 s later, it is sailing 30.0° north of east at a speed of 3.50 m/s. During this time, three forces act on the boat: a 34.4-N force directed 10.0e north of east (due to an auxilary engine), a 20.9-N force directed 10.0° south of west (resistance due to the water), and E (due to the wind). Find the (a) the...
