What is your velocity relative to the bus?

Click For Summary

Homework Help Overview

The problem involves relative velocity, specifically determining the velocity of a person walking towards or away from a bus that is moving in traffic. The subject area is kinematics, focusing on the addition and subtraction of velocities in different frames of reference.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants discuss how to calculate the relative velocity of the person with respect to the bus and the ground, questioning the steps involved in the process. There are attempts to visualize the problem through vector drawing and to clarify the setup of the scenario.

Discussion Status

Some participants have provided guidance on how to approach the problem, including drawing vectors and considering the frame of reference. There is a mix of interpretations regarding the calculations, with some participants expressing uncertainty about their answers.

Contextual Notes

Participants mention that the problem was assigned by a teacher and that they have encountered similar questions, indicating a potential lack of familiarity with the concepts involved. There is also a suggestion that the problem may not be from a textbook, which could imply varying levels of exposure to the topic.

It's rush hour, you are heading home, and your bus is suck in traffic. It is moving 2 m/s. you get frustrated and decide to walk towards the front of the bus at 4 m/s. What is your new velocity relative to the ground?

a. what is your velocity relative to the bus?

b. what if you decided to walk 4 m/s backwards?

can someone help me solve this. I have many problem like this but don't know the steps to it.
Thanks ;] <3

is there anyone that can help me on this question?
 


Draw out the vectors. If the bus is heading forward at 2 m/s with respect to the ground, and you walk 4 m/s forward with respect to the bus, what speed would a person standing on the ground away from the bus see you moving at (with respect to the ground)? It's kind of hard to explain without giving the answer away. There must be at least one example of this in your textbook.
 


it's not a textbook because a teacher just gaves us questions.
 


is the new velocity 6 m/s?
 


=====> 2m + =======>4m rights?
 


b should be.

=====> 2m/s
<===== 4m/s


= -2m/s?
 


nevermind i did it again and got.

a. 2m/s

b. 6m/s

right?
 


Your first answers were correct. Why did you change them?
 
  • #10


so that mean a is 6 m/s and b is -2 m/s?
