SUMMARY

The discussion focuses on calculating the resultant velocity of two equal velocities of 100 km/h that are oriented at right angles to each other. The correct approach involves using vector addition, specifically applying the Pythagorean theorem. The resultant velocity is determined to be approximately 141.4 km/h, which is derived by multiplying one of the velocities by the square root of 2. This calculation confirms that the resultant velocity increases when two equal vectors are combined at right angles.

PREREQUISITES
  • Understanding of vector addition
  • Familiarity with the Pythagorean theorem
  • Basic knowledge of velocity as a vector quantity
  • Ability to interpret graphical representations of vectors

can someone help me with this question:
Calculate the resultant velocity of a pair if 100 km/h velocities at right angles to each other

i don't even understand what the question is asking me

Velocities are represented with vectors, so use http://www.codesampler.com/d3dbook/chapter_02/chapter_02_files/image012.jpg" . However, for different vector orientations, you get different resultant velocities.

k thank you, that helped a lil...would this be the right answer then:

Since both velocities are equal we have to times one of the sides by the square root of 2. Which means that the reluctant velocity is 141.4.
