The boat is steered upstream to maintain a path directly across the river.
A boat can travel at a constant speed of \(5.0 \text{ m/s}\) relative to the water. The boat is used to cross a river where the current flows at a constant speed of \(3.0 \text{ m/s}\) relative to the riverbank. In order to travel along a path that is exactly perpendicular to the riverbank, the pilot aims the boat at an angle upstream. What is the magnitude of the boat's velocity relative to the riverbank?
