Homework Help Overview

The discussion revolves around calculating the force required to accelerate a 5.0g object at an acceleration of 11000 g's, specifically in the context of a centrifuge. The original poster expresses uncertainty about how to proceed without additional information such as rpm or diameter.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the application of Newton's second law and the conversion of acceleration from g's to standard units. There are questions about the necessity of converting mass from grams to kilograms for the calculations.

Discussion Status

The conversation includes attempts to clarify the correct approach to calculating force, with some participants providing insights on unit conversions and the relationship between mass and acceleration. There is acknowledgment of a misunderstanding regarding the conversion process, but no explicit consensus has been reached on the overall method.

Contextual Notes

Participants note the lack of specific parameters such as rpm or diameter, which may affect the calculation. There is also a discussion about the implications of using different units for mass and acceleration.

Force required to accelerate 5.0g object at 11000 g's. (in a centrifuge)
But it does not give me rpm or diameter so how can i calculate the force?

Im assuming it really doesn't matter that its in a centrifuge? Any leads would help

Write down the equation of force using Newton 2. What is the value of the centripetal acceleration?
 
F= M* A

I tried converting the acceleration out of G's by dividing 11000 by 9.8 then times it by 5... Do i need to convert the mass out of grams and into KG?

A "G" is shorthand for the acceleration of gravity, 1 G is 9.8m/s^2 acceleration. You've got 11000 G's...you should be multiplying, not dividing. And yes, if you want your answer in the basic SI force unit of Newtons, mass must be expressed in kilograms.
 
Awsome i got it. Thank you so much phanthom jay i was dividing the 11000/ 9.8 rather than multiplying ;)
