Discussion Overview

The discussion revolves around solving a physics problem related to the motion of a stone and a bird, specifically addressing the challenge of not using projectile equations. Participants explore alternative mathematical approaches and the relationships between the given parameters.

Discussion Character

  • Homework-related, Exploratory

Main Points Raised

  • One participant expresses uncertainty about how to approach the problem without using projectile equations and mentions a lack of knowledge regarding the necessary mathematical equations.
  • Another participant points out that the initial post lacks a clear statement of the question and an attempt at a solution.
  • A subsequent reply suggests starting with known information about the motion of the stone and bird and recommends drawing a diagram to aid understanding.
  • A participant notes that the only given value is the velocity of the bird and questions its relation to the projectile equations, which typically involve angle, velocity, distance, and time.
  • One participant describes the motion of the stone as parabolic and suggests that a graph of displacement versus time for both the stone and the bird might be helpful.

Areas of Agreement / Disagreement

Participants do not reach a consensus on how to solve the problem, and multiple viewpoints regarding the approach to take remain evident.

Contextual Notes

The discussion lacks a clear definition of the problem statement and the specific relationships between the parameters involved, which may affect the proposed approaches.

Homework Statement



How can you solve this? I have no idea, anything. There's a clue that it cannot be solved by the projectile equations. It can be solved using math equations. I do not know them.

Apart from missing any attempt at a solution - I think you are also missing the question
 


sorry I forgot
 


Start by writing down what you know about the motion of the stone and bird, then drawing a diagram will help
 


I already have the diagram but there is only one given, the velocity of the bird.
From the projectile equations, the values included are the angle, velocity, x distance, y distance, and time. I do not know what is the relation of the velocity of the bird to the projectile equations.
 


So the stone flies in a parabola
Drawn across this, half way up, you have the flight of the bird from the point that the stone was going up to the point it was coming back down.

It might help to sketch a graph of displacement / time for the stone and the bird
