Calculating Distance Downstream with Relative Velocity

Click For Summary
SUMMARY

The discussion centers on calculating the downstream distance a rowboat travels while crossing a river with a current. The rowboat has a velocity of 3.30 mi/h at an angle of 62.5 degrees North of west, while the river current flows eastward at 1.25 mi/h. The river width is 0.505 miles. The calculations confirm that the boat will indeed drift downstream despite its angle and speed, contradicting initial assumptions that it may go upstream.

PREREQUISITES
  • Understanding of vector components and relative velocity
  • Familiarity with trigonometric functions for angle calculations
  • Knowledge of basic physics principles related to motion in fluids
  • Ability to perform calculations involving distance, speed, and time
NEXT STEPS
  • Study vector decomposition in physics to analyze motion in multiple dimensions
  • Learn how to apply trigonometric functions to resolve velocities into components
  • Research fluid dynamics principles affecting objects in moving water
  • Explore real-world applications of relative velocity in navigation and boating
USEFUL FOR

Students in physics, maritime navigators, and anyone interested in understanding the effects of currents on boat navigation.

I can't help but think maybe there's extraneous info??

Question:
A rowboat crosses a river with a velocity of 3.30 mi/h at an angle of 62.5 degrees North of west relative to the water. The river is .505 mi wide and carries an eastward current of 1.25 mi/h. how far downstream is the boat when it reaches the opposite shore?

No information looks extraneous, are you sure you listed the numbers right? As it is now it looks as if the boat would actually go upstream by the time he reached the other side
