Is -4m the correct displacement for average velocity calculation?

Click For Summary
SUMMARY

The average velocity calculation after 11 seconds is based on a total displacement of -4 meters, as confirmed by the graph analysis. The formula used is v = d/t, where 'd' is the displacement and 't' is the time. The negative sign indicates the direction of the displacement, which is crucial for accurate velocity representation. Therefore, the assumption of -4 meters for displacement is correct.

PREREQUISITES
  • Understanding of basic kinematics principles
  • Familiarity with the formula for average velocity (v = d/t)
  • Ability to interpret displacement graphs
  • Knowledge of vector quantities and their significance in physics
NEXT STEPS
  • Study the concept of displacement versus distance in physics
  • Learn about vector representation of velocity and its directionality
  • Explore graphing techniques for visualizing motion in physics
  • Review examples of average velocity calculations in different scenarios
USEFUL FOR

This discussion is beneficial for students studying physics, particularly those focusing on kinematics and average velocity calculations, as well as educators looking for clear examples of displacement analysis.

Homework Statement


Calculate the average velocity after 11 s.

Homework Equations


v=d/t

The Attempt at a Solution


I need to find the total displacement to find average velocity. I assumed the displacement was -4 as the graph goes up then back down to 0 then -4 so total is just -4. Is that a correct? Thank you!

Yes, based on your graph, the magnitude of the displacement during the 11 sec is ##-4\text{m},## so you can calculate its average velocity and don't forget its direction.
