A boat is traveling at 14 km/h with respect to the water of a river in the upstream direction:
1. What is the speed of the river current if the boat’s speed relative to the ground is 9 km/h?
2. How is the boat’s speed affected when traveling against the river current, and what is the resulting velocity relative to the ground?
3. Explain the concept of upstream and downstream motion in the context of river travel.
4. If the boat were to travel downstream, how would the river current impact its speed and the overall velocity relative to the ground?
5. Discuss any strategies or adjustments the boat operator might employ to navigate effectively in the presence of the river current.
Provide a detailed analysis of the boat’s motion, considering the interplay between its speed, the river current, and the resultant velocity relative to the ground.
