Finding magnitude of displacement vector

Click For Summary
SUMMARY

The discussion focuses on calculating the magnitude of a displacement vector resulting from two movements: 1.5 meters East and 3.2 meters South. The correct magnitude is determined using the Pythagorean theorem, yielding a result of 3.53 meters. Participants confirm that the term "magnitude" refers to the size of the vector, which is always a positive value. The calculation must include correct units and be accurate within 0.02 meters.

PREREQUISITES
  • Understanding of vector addition
  • Familiarity with the Pythagorean theorem
  • Basic knowledge of displacement and magnitude concepts
  • Ability to work with units of measurement
NEXT STEPS
  • Study vector addition techniques in physics
  • Learn more about the Pythagorean theorem applications
  • Explore concepts of magnitude in physics and mathematics
  • Practice problems involving displacement vectors and their magnitudes
USEFUL FOR

Students in physics or mathematics, educators teaching vector concepts, and anyone interested in understanding displacement and magnitude calculations.

[solved] finding magnitude of displacement vector

Silas crawls 1.5 meters due East then crawls 3.2 meters due South. Find the magnitude of the net displacement vector. Make sure you do the following in your answer:

* include correct units
* make your answer correct within 0.02
* make your answer positive (because magnitudes are always considered positive)
* put your answer in a form like one of these:
o #.## m
o #.## meters

The question is worth one point, and there is a half point penalty for each incorrect submission.

i got a resultant vector of 3.534m but that was using pythagorean theorem (1.5squared+3.2squared)= 12.49---> square root 12.49=3.53 but i don't know what it means by magnitude...am i doing it right?

Magnitude just means size. It is exactly what you calculated.
