Homework Help Overview

The discussion revolves around identifying position-versus-time curves that represent the motion of an object with negative acceleration. Participants are considering various lines labeled (a) through (e) in a provided figure.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants are questioning which specific curves correspond to negative acceleration and are discussing the reasoning behind their choices. There is an emphasis on understanding the underlying concepts rather than simply seeking answers.

Discussion Status

Some participants are seeking clarification on the problem and expressing a desire for guidance without directly asking for answers. Others are encouraging a deeper exploration of the concepts involved, emphasizing the importance of understanding the reasoning behind the answers.

Contextual Notes

There is a mention of forum rules that discourage providing direct answers to homework questions, suggesting that participants should engage with the problem to a certain extent before seeking help.

What's your reasoning?
 
Well, I wish to know what the answer is and how to get it.

I think he wants to know what exactly are you having a problem with in your question. Where exactly do you get stuck at? It wouldn't help you much if we just gave you the answer without making sure you understand HOW to get it. :smile:

Edit: PF rules don't let us just give people the answers to homework questions. Get as far as you can in the problem and then explain how you got there and what you don't understand if you can. Then we can help you!

Here's a hint: What does the slope of the curve tell you?
