Homework Help Overview

The discussion revolves around projectile motion and free body diagrams, specifically focusing on scenarios involving objects in projectile paths and rockets landing on the moon.

Discussion Character

  • Exploratory, Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants explore the relationship between initial and final speeds in projectile motion, questioning the effects of direction on velocity. They also discuss the forces acting on a rocket during landing and the implications of these forces on acceleration.

Discussion Status

The conversation is active, with participants confirming each other's thoughts and probing further into the implications of forces and acceleration. There is a focus on understanding the direction of acceleration in relation to the forces acting on the rocket.

Contextual Notes

Participants are navigating assumptions about forces and motion without definitive conclusions, indicating a learning process that involves questioning and clarification of concepts.

Homework Statement



1. If an object is shot in a projectile path and its initial and final height is the same what is true.

2. If a rocket vertical is landing on the moon it shoots a bit of the rocket fuel while landing what is the correct Free body diagram.



The Attempt at a Solution


1.Well I know velocity initial and final cannot be the same because it has different directions.
So I would say initial and final speed are the same, and acceleration is constant right?


2. It would be a rocket with a greater downward force than upward force correct?

Right.
2. It would be a rocket with a greater downward force than upward force correct?
If the downward force is greater than the upward force, in what direction is the acceleration?

Right.

If the downward force is greater than the upward force, in what direction is the acceleration?

net force would be down therefore acceleration would also be down so I guess that answer is correct
 
If the acceleration is down and the velocity is also down because the rocket is landing, does the speed increase or decrease?
