Homework Help Overview

The discussion revolves around finding the equation of a variable 'c' in the context of a moving wedge problem involving a particle. The original poster references a specific question from their homework, indicating that they have gathered necessary equations but are struggling with this particular aspect.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • The original poster attempts to derive the equation for 'c' but expresses uncertainty about the problem's setup, suggesting a potential error in the question itself. Other participants question the completeness of the provided information and the assumptions made regarding the forces involved.

Discussion Status

Participants are actively engaging with the problem, with some providing feedback on the original poster's attempts. There is a recognition of possible oversights in the problem statement, particularly concerning the neglect of tension in the string, which may influence the equation being sought.

Contextual Notes

The original poster mentions that part 'c' is critical for solving subsequent parts of the problem, indicating a potential dependency on this equation for overall understanding. There is also a note about the attachment not initially containing the relevant question, which may have hindered the discussion.

I have obtain all eqtn I need but I cannot figure out how to get the equation of c.
I have been trying for few days and my friends tell me that it is possible that Dr made a mistake. Since without part c, we can still do part d easily.

Can anyone help me to see weather there are any error in the question?

Your attachment doesn't seem to have Q2 in it.
 
I have fixed the problem now
 
My only comment is that your equation for the wedge neglects the tension in the string.
 
Thx very much!
