To explain:The navigation of boat in terms of the velocity relative to the water.
Answer to Problem 39SSC
The boat has to navigate with the velocity relative to the shore
Explanation of Solution
Given:
The motion of a boat across a fast-moving river is shown below.
Consider the boat has to cross the river to reach the shore. The velocity of the boat relative to the flowing river denoted by
In order to reach the shore, the boat should move with a velocity relative to the shore
The vector diagram showing the boat’s velocity is shown below.
From the vector diagram, the resultant of the velocity of water relative to the shore and the velocity of boat relative to the water gives the velocity of boat relative to the shore. The dotted lines show the velocity of the boat relative to the shore
Conclusion:
Thus, the boat has to navigate with the velocity relative to the shore
