Homework Help Overview

The discussion revolves around the application of conservation of linear momentum in a physics problem, particularly in the context of forces acting on an object. Participants are examining the implications of gravity on momentum conservation during a specific event, likely an explosion.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants are questioning the conditions under which conservation of momentum applies, particularly regarding the presence of gravitational force. There is a suggestion that the problem may not have been clearly presented, leading to confusion about the application of these principles.

Discussion Status

Some participants are exploring the nuances of the problem, particularly how gravity interacts with momentum conservation. There is acknowledgment of the need for clearer problem presentation, and some guidance has been offered regarding the interpretation of the scenario described.

Contextual Notes

There is mention of a potential missing illustration or problem statement, which may be affecting the clarity of the discussion. Participants are also navigating the implications of gravity in the context of the problem, which may not have been fully articulated.

I reckon that we only apply conservation of linear momentum for object which has total net force acting on equal zero but in this case , the gravity force still exist , total net force is mg
Thank in advance

Is there a missing illustration? Because you haven't presented a problem.
 
I was not upset; I was only pointing out why you were not getting replies.

I think I understand your concern. The question seems to me to be written to avoid the force of gravity by stating "right after the explosion." The focus is on momentum. Gravity only enters into what you posted in the Exercise, even then it's a path that's straight up and down and only asks about "the center of mass."
