Homework Help Overview

The problem involves two students on roller skates pushing each other away, with differing masses of 90 kg and 60 kg. The task is to find the ratio of their velocities after they lose contact.

Discussion Character

  • Exploratory, Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants discuss the application of conservation of linear momentum as a potential approach to the problem. Some express confusion about the concept of linear momentum itself.

Discussion Status

Some hints regarding the conservation of momentum have been provided, but there is a lack of clarity among participants, with at least one expressing confusion about the fundamental concepts involved.

Contextual Notes

There appears to be a gap in understanding the definition of linear momentum, which may affect the discussion. Additionally, the informal tone suggests a collaborative environment where participants are seeking to clarify concepts.

Hint-Does conservation of linear momentum tell you something? :)
 
HINT: Conservation of momentum.

Edit: Damn it too slow!
 
huh? i don't get it
 
You don't know what the linear momentum is?

PS- Sorry, Hootenanny :approve: .
