SUMMARY

The resultant velocity of a boat moving at 10 m/s south (160 degrees) in a river flowing at 3 m/s east (90 degrees) can be calculated using vector addition. By representing the velocities as vectors and applying trigonometric principles, the resultant velocity can be determined. The correct angle for south is 180 degrees; however, in this context, 160 degrees indicates a slight eastward deviation from true south.

PREREQUISITES
  • Understanding of vector addition
  • Knowledge of trigonometry
  • Familiarity with coordinate systems
  • Basic physics concepts related to motion
NEXT STEPS
  • Study vector addition techniques in physics
  • Learn how to apply trigonometry to resolve vectors
  • Explore graphical methods for vector representation
  • Investigate real-world applications of resultant velocity in navigation
USEFUL FOR

Students in physics, navigators, and anyone interested in understanding motion in fluid dynamics.

Say I have a boat moving at 10 m/s south (160 degrees) ina river that is flowing at 3 m/s east (90 degrees)

How would you calculate the resultant velocity in this instance?

Do you know about trigonometry and vectors? (hint: draw the velocities as vectors)

(by the way, are you sure you don't mean 180 degrees when you said "south"?)
