Translating acceleration into distance traveled

Click For Summary

Homework Help Overview

The discussion revolves around calculating the distance traveled by an object under constant acceleration, specifically in the context of a car accelerating at 2 m/s² for 20 seconds. The original poster is seeking guidance on the relevant equations and methods to determine distance when starting from zero velocity.

Discussion Character

  • Exploratory, Conceptual clarification, Mathematical reasoning

Approaches and Questions Raised

  • The original poster attempts to relate acceleration and time to final velocity but expresses uncertainty about incorporating position into the calculation. Some participants suggest looking up Newton's equations of motion and offer to derive them. Others provide specific equations for uniform motion under constant acceleration.

Discussion Status

Participants are actively discussing the relevant equations for the problem, with some providing specific formulas for calculating distance. There is a mix of attempts to clarify concepts and offer guidance, but no consensus has been reached on a single approach yet.

Contextual Notes

The original poster indicates a lack of familiarity with the relevant equations and is working within an algebra-based physics course framework. There may be constraints related to the level of detail expected in the responses.

Homework Statement



If something is moving at a constant acceleration (starting from 0 velocity) for a known period of time, how do you figure how far they've traveled? Eg. a car is accelerating at 2 m/s^2 for 20 seconds.

I'm taking an algebra based physics course.

Homework Equations



I do not know which equation are relevant.

The Attempt at a Solution



I know I can multiply time by acceleration and get a final velocity. for example the final velocity is 40 m/s in my example. I don't know how to factor position into it.

Look up Newton's equations of motion

I can tell you how to derive them if you wish.
 
Hello,

I think the equations you need are those we use for uniform motion, ie when the acceleration is constant.

Assuming all the motion is one direction only the distance traveled will be [tex]s=v_{0}t + \frac{at^{2}}{2}[/tex]

where [tex]v_{0}=initial\ velocity\; a=acceleration\; t=time\ elapsed\; and\ s=distance\ traveled[/tex]

Also [tex]v_{1}^{2}-v_{0}^{2}=2as[/tex]

Thanks that works
