Homework Help Overview

The discussion revolves around a problem in projectile motion, specifically concerning the height a stone reaches when thrown vertically upwards, given a total time of 30 seconds for its ascent and descent.

Discussion Character

  • Exploratory, Conceptual clarification

Approaches and Questions Raised

  • Participants explore the application of accelerated linear motion equations to determine the height of the stone. Some express a need for clarification on these equations, while others suggest that the original poster should be able to derive the answer independently.

Discussion Status

The discussion is active, with participants offering guidance on the relevant equations and concepts. There is a mix of attempts to provide direct assistance and encouragement for self-sufficiency in problem-solving.

Contextual Notes

Participants note the need for specific equations related to accelerated linear motion, and there is a reference to a resource in the PF Library for further information.

Hi there,

Come on. I believe you can answer that by yourself. You just need to apply the accelerated linear motion equations and you get to your answer
 
can u provide that linear accelerated motion...
 
Not really, but I can help you find them.

Acceleration is define as a variation of speed: [tex]a = \frac{v_1 - v_0}{t}[/tex]

In the case of accelerated linear motion, the average speed is equal to the mean speed: [tex]\overline{v} = \frac{v_0 + v_1}{2}[/tex]

From these three equations, you have the solution to your question.
