Homework Help Overview

The discussion revolves around calculating kinetic energy (KE) in the context of potential energy (PE) values provided, specifically 15000 J and 11250 J. Participants are exploring the relationship between these forms of energy, particularly in scenarios involving a falling body.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants are questioning how to derive KE from the given PE values and whether additional context, such as the scenario of a falling body, is necessary for a meaningful calculation. There is an emphasis on understanding the underlying principles rather than simply obtaining an answer.

Discussion Status

Some participants have prompted the original poster to clarify their approach and provide equations or attempts at solving the problem. There is an ongoing exploration of the assumptions behind the potential energy values and their application to kinetic energy calculations.

Contextual Notes

There is a suggestion that the potential energy values may lack context without a specific problem scenario, such as a body in motion or falling, which could influence the calculation of kinetic energy.

Energy Question?

OK let's say that PE=15000 or 11250 J (J=Joules) how would you find out what the KE is?

just want to find out how to get the Kinectic Energy?

You need to show equations and an attempt at the answer

Saying that potential energy is 11250J is meaningless really.
Is there some sort of problem associated with the potential energy? A body falling? Something of that sort?
 
ok then let's say it's a body falling how do i answer this...i don't want you to give me the answer i need help so i can understand this and solve it to get the answer on my own...
