Homework Help Overview

The discussion revolves around a tube train journey where the train covers a distance of 432 meters from rest to rest in one minute. The journey involves three stages: acceleration, uniform motion, and deceleration, with specific rates of acceleration and deceleration provided.

Discussion Character

  • Exploratory, Assumption checking, Mathematical reasoning

Approaches and Questions Raised

  • Participants discuss the need for relevant kinematic equations and how to apply them to find the time taken in each stage of the journey. There is a focus on understanding the problem setup and the relationships between distance, acceleration, and time.

Discussion Status

Some participants emphasize the importance of showing work and understanding the problem rather than seeking direct answers. There is a recognition of the need for relevant equations, and participants are encouraged to articulate their thoughts on the problem to facilitate guidance.

Contextual Notes

One participant notes that there are specific forum rules regarding homework help, indicating that users should engage more actively in the problem-solving process rather than seeking complete solutions.

HELP! Answer pls ^^

a tube train covers 432m from rest to rest in 1 minute. It first accelerates 1/3 m/s2 then goes uniformly and finally retards at 1 m/s2. Find the time taken in each of the three stages of the journey.

PLEASE HELP ^^ CONFUSED ON WHAT FORMULA AND HOW TY...

We don't just give out answers here, sorry. We help with homework. We do not do homework. I already made it through intro physics! In order to get help on this forum you are going to have to show some work, sorry. It's the rules. You must have know SOMETHING about the problem. If your that stuck with finding an equation to use, list what you know and what you want to find and find an equation that has those quantities in it. Give me your thoughts on the problem at least. I need something in order to best know what is stumping you.

Also, There is a special forum for homework questions, please post your future homework questions there.
 
Sorry new at this ^^ won't happen again : )

Fair enough. Now, can you list the relevant kinematic equations that you should use for this problem? How should you apply them?
