Homework Help Overview

The discussion revolves around calculating the acceleration due to gravity on a fictional planet, Zond 4, which is described as having a mass one third that of Earth and a radius one quarter of Earth's radius.

Discussion Character

  • Exploratory, Conceptual clarification, Mathematical reasoning

Approaches and Questions Raised

  • Participants discuss the need for an appropriate equation to calculate gravitational acceleration, with suggestions to refer to physics textbooks for foundational equations. There is also a mention of using specific gravitational field strength equations.

Discussion Status

The conversation is ongoing, with some participants providing hints and encouraging the original poster to explore relevant equations. There is no explicit consensus on a solution yet, but guidance has been offered to look for appropriate formulas.

Contextual Notes

Participants note the fictional nature of Zond 4 and imply that the original poster may not have access to textbooks, which could influence the discussion's direction.

The planet Zond 4(made up) has a mass which is one third the mass of the earth, and a radius which is one quarter of the Earth's radius.

What is the accelerationdue to gravityon the surface of Zond 4?

Thanks

Don't you think is better to turn over your physics book before you post? What you need for this problem is a very, very elementary equation. Search your book and give us some equations you find appropriate for this problem. After that we'll find a solution!
 
If you are doing this for the sake of physics :biggrin:, and don't have the textbooks (otherwise you might have posted on the homework threads), then I'll give you a start.

The gravitational field strengh equation

[tex]E_{g.field}=4\pi G \frac{m}{4\pi r^2}[/tex]

Use kilograms and meters and plug in the numbers. :wink:

Well of course he is! Didn't you hear about the recent discovery of the planet Zond 4? :smile:
 
Haha, yes of course!
