Relative Velocity: Bird and Train Perspective

Click For Summary
SUMMARY

The discussion centers on calculating the relative velocity of a bird flying north at 15 m/s and a train traveling east at 15 m/s. The correct magnitude of the bird's velocity from the train's perspective is 21.2 m/s at a direction of 45 degrees north of west. Although one participant noted a discrepancy in the directional description, both interpretations effectively convey the same relative motion. This highlights the importance of precise terminology in physics problems.

PREREQUISITES
  • Understanding of vector addition in physics
  • Familiarity with relative velocity concepts
  • Basic knowledge of trigonometry
  • Ability to interpret directional angles
NEXT STEPS
  • Study vector addition techniques in physics
  • Learn about relative velocity in different frames of reference
  • Explore trigonometric functions related to angles and distances
  • Practice problems involving relative motion scenarios
USEFUL FOR

Students studying physics, educators teaching kinematics, and anyone interested in understanding relative motion and vector analysis.

PROBLEM 5: A bird is flying due north with a speed of 15 m s. A train is traveling due east with a speed of 15 m s. What are the magnitude and direction of the velocity of the bird from the point of view of a passenger in a trai


ok so I got an answer of 21.2 m/s 45 degree west of north...
the answer at the back was 45 degrees north of west...
does it matter?
