Homework Help Overview

The discussion revolves around the motion of two balls exiting a semi-circular tube system, focusing on the conservation of momentum and the effects of their velocities as they leave the system. The problem involves analyzing the resultant velocities of the balls and the system, considering various assumptions about mass and direction.

Discussion Character

  • Exploratory, Conceptual clarification, Mathematical reasoning, Assumption checking

Approaches and Questions Raised

  • Participants explore the implications of momentum conservation in both vertical and horizontal directions, questioning the setup and assumptions regarding angles and energy distribution. There are discussions about the symmetry of the scenario and how it affects the momentum calculations.

Discussion Status

The conversation is active, with participants providing insights and questioning each other's reasoning. Some guidance has been offered regarding the distinction between momentum and kinetic energy, and there is an ongoing exploration of the implications of the problem's assumptions.

Contextual Notes

Participants note the assumption of 100% efficiency and the implications for momentum and energy conservation. There are discussions about the angles involved and the potential need for additional equations to fully address the problem.

Beware! Your 'or' worries me...

There is a big difference between kinetic energy and momentum.

In elastic collisions there is conservation of kinetic energy. (this is what I was fishing for - didn't want to just give it away)
In all collisions there is conservation of momentum.

Now, do you have a battle plan to conclude this exercise ?

thank you Sir for your patience and help.
