How Do Kinetic and Potential Energies Change During a Ball's Ascent?

Click For Summary

Homework Help Overview

The discussion revolves around the changes in kinetic and potential energies of a ball thrown upward, specifically focusing on its energy states at different points during its ascent. The problem involves calculations related to energy conservation and motion in the context of physics.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants are attempting to determine the kinetic and potential energies at a specific distance during the ball's ascent, as well as the speed at that point. Questions about the kinetic energy at maximum height and the method to find maximum height are also raised.

Discussion Status

The discussion is in an early stage, with some participants expressing uncertainty about their understanding and others suggesting starting points for analysis. There is no clear consensus yet, but guidance has been offered regarding the maximum height and energy considerations.

Contextual Notes

Participants are working under the constraints of a homework assignment, which may limit the information they can share or the methods they can use. There is also an emphasis on understanding the relationships between kinetic and potential energy in this context.

Homework Statement


a .50 kg ball thrown upward has an initial Kinetic energy of 80 J.


Homework Equations



(a)what are its kinetic and potential energy when it has traveled 3 quarters of the distance to its maximum height?
(b) speed at this point?
(c) potential energy at the maximum height (assume a reference is chosen to be zero at the launch point)?

The Attempt at a Solution


pls reply...i nid it badly...thnks...im working on it now..
 
Physics news on Phys.org
Please show your attempt.
 
i don't have an idea honestly
 
Start by finding the maximum height. What is the kinetic energy at the maximum height?
