A stick of length 1.7 m is aligned in the east-west direction. A force acts
on the east end of the stick, and has magnitude 650 N and is directed 30
degrees south of east. Determine the magnitude of the force's torque about
a vertical axis at the west end of the stick.

319-kg boat is sailing 14.5° north of east at a speed of 1.84 m/s. Thirty seconds later, it is sailing 33.9° north of east at a speed of 4.12 m/s. During this time, three forces act on the 34.2-N force directed 14.5° north of east (due to an auxiliary engine), a 23.5-N force directed 14.5° south of west (resistance due to the water), and Fw (due to...
