HEADING is the direction you point a boat or plane
BEARING is the angle you measure to a lighthouse FROM your boat or plane.
That said:
V across = 2.11
V down stream = 1.84
|V| = sqrt (2.11^2 + 1.84^2)
|V| = 2.8 m/s
A boat crosses a river of width 98.4 m
in which the current has a uniform speed of 1.84 m/s. The pilot maintains a bearing (i.e.,the direction in which the boat points) perpendicular to the river and a throttle settingto give a constant speed of 2.11 m/s relative
to the water.
What is the magnitude of the speed of the boat relative to a stationary shore observer?
Answer in units of m/s.
