Homework Help Overview

The discussion revolves around a problem related to collisions, specifically focusing on elastic collisions and the conservation of kinetic energy and momentum. Participants are exploring the assumptions and definitions related to these concepts.

Discussion Character

  • Exploratory, Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants question the assumption that each piece in the collision receives the same amount of energy. There is a request for clarification on how to approach the problem, and discussions about the definition of elastic collisions are initiated. One participant mentions setting up simultaneous equations based on conservation laws.

Discussion Status

The discussion is active, with participants seeking clarification on assumptions and definitions. Some have shared their attempts at calculations, while others are encouraging further exploration of the problem by requesting additional details or workings.

Tell me why you think you can assume that each piece gets the same amount of energy?

Im not going to lie. I guessed. Wish to give me a better idea of how to tackle this?
 
What is the definition of an elastic collision?

Ah...

so what I have done is conserves ALL of the kinetic energy! This let's me set up some simultaneous equestions with the momentum and all the kinetic energy conserved.

This gives me: v1 = 254.4m/s

and v2 =46.2 m/s.

does this seem correct (i havnt got the answer!) i can post all the workings if that helps.
 
Go ahead and post the work.
