A small boat with a speed of 23km/h relative to the water is
sailing in a sea which has a speed of 15 km/h relative to the shore
in a direction E 16 N. What direction is the boat heading
(relative to the water) if it is going in a direction N 32.7 E
(relative to the shore)?
Hint: Suggested steps: Interpret the situation in terms of the
relative velocity equation, indicating the meaning of all the
subscripts. Draw a diagram roughly to scale, including all of the
known information and using the parallelogram rule, on the
coordinate system below. Solve for unknowns using geometry and sine
and cosine laws.
Here we apply concept of relative velocity and trigonometry as well as vector addition.
