Homework Help Overview

The discussion revolves around calculating escape speeds and final velocities related to a small asteroid. The original poster presents two questions: one regarding the final speed of a rock thrown from the asteroid and another about the initial speed needed to ensure the rock travels away at a specific final speed.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants are exploring the relationship between escape speed and the velocities of objects thrown from the asteroid. There are questions about how to set up the problem and incorporate initial and final velocities into relevant equations.

Discussion Status

The discussion is in an early stage, with participants seeking clarification on how to approach the problem. Some guidance has been offered regarding the escape speed formula, but there is no consensus on the setup or methodology yet.

Contextual Notes

Participants have noted a lack of clarity in the problem setup and expressed uncertainty about the correct forum for posting. There may be assumptions about the parameters involved that have not been fully articulated.

1. The escape speed from a very small asteroid is only 32 m/s. If you throw a rock away from the asteroid at a speed of 37 m/s, what will be its final speed?

2. How fast (relative to you) do you have to throw the rock (in the direction of the asteroid's spin) so that it never comes back to the asteroid and ends up traveling at a speed of 8 m/s when it is very far away? (I have mass, radius, and escape speed; I just need to know how to set it up)

THANKS

I the future post homework help requests in the homework help forums.


Now, Show us that you have tried.
 
i know that Ve = sqrt((2GM/r))
but i don't know how to incorporate the final and initial velocities into the equation
 
i apologize for placing it in the wrong forum

i'm new to the site
