Homework Help: Physics

Posted by Natasha on Sunday, February 12, 2012 at 12:43am.

A 343-kg boat is sailing 16.2 north of east at a speed of 1.98 m/s. Thirty seconds later, it is sailing 37.5 north of east at a speed of 3.76 m/s. During this time, three forces act on the boat: a 30.3-N force directed 16.2 north of east (due to an auxiliary engine), a 22.3-N force directed 16.2 south of west (resistance due to the water), and W (due to the wind). Find the magnitude and direction of the force W. Express the direction as an angle with respect to due east.
