A boat crosses a river of width 68.3 m in which the current has a uniform speed of 2.01 m/s. The pilot maintains a bearing (i.e., the direc- tion in which the boat points) perpendicular to the river and a throttle setting to give a constant speed of 2.69 m/s relative to the wa- ter. What is the magnitude of the speed of the boat relative to a stationary shore observer? A boat crosses a river of width 68.3 m in which the current has a uniform speed of 2.01 m/s.
