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.

A woman sailing a boat at night is following directions to a dock. The instructions read to first sail 27.5 m in a direction 66.0o north of east from her current location, and then travel 30.0 m in a direction 112o north of east (or 22.0o west of north). If the woman makes a mistake and travels in the opposite direction for the second leg of the trip, where will she end up? Compare this location with the location of...

A rescue plane flies horizontally at a constant speed searching for a disabled boat. When the plane is directly above the boat, the boat's crew blows a loud horn. By the time the plane's sound detector receives the horn's sound, the plane has traveled a distance equal to one-third its altitude above the ocean. Assuming it takes the sound 2.02 s to reach the plane, and taking the speed of sound to be 343 m/s, determine the following. (a) the...
