What is the resultant displacement of John on the interstate highway?

Click For Summary

Homework Help Overview

The problem involves calculating the resultant displacement of John as he travels along an interstate highway, starting from a mile marker of 244 km, moving to 145 km, and then to 179 km. The focus is on understanding displacement in the context of linear motion.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the concept of vector addition and the importance of comparing starting and ending points to determine displacement. There is uncertainty about the correctness of initial attempts and answers.

Discussion Status

The discussion includes various attempts at finding the resultant displacement, with some participants providing numerical answers. There is a mix of expressions of gratitude and encouragement, indicating a supportive environment. However, no consensus on the correct answer has been reached.

Contextual Notes

Participants are navigating the problem without explicit guidance on the equations or methods, relying on their interpretations of displacement and vector addition.

Hi everyone my first post! Iam stuck in this problem idk if iam getting the answer right. My solution was 133 is this correct? Thanks for your help.

Homework Statement


While John is traveling along a straight interstate highway, he notices that the mile marker reads 244 km. John travels until he reaches the 145 km marker and then retraces his path to the 179 km marker.
What is John's resultant displacement from the 244 km marker? Answer in units of km.

Can anyone help me please?
 
This has to do with vector addition.

The easiest way to do this problem would be to compare the starting and ending points. The answer you're trying to find is the difference between final position and initial position.
 
I got it man is -65. THANKS! I really appreciate it let's c if i don't get stuck in any other questions lol.
 
No problem
