A boat crosses a river of width 152 m in whichthe current has a uniform speed of 0.82 m/s.The pilot maintains a bearing (i.e., the direc-tion in which the boat points) perpendicularto the river and a throttle setting to give aconstant speed of 1.4 m/s relative to the wa-ter.What is the magnitude of the speed of theboat relative to a stationary shore observer?Answer in units of m/s.
