Solve Physics Homework: Car Stopping Distance

Click For Summary

Homework Help Overview

The problem involves a car traveling at an initial speed with a known deceleration, and the goal is to determine the stopping distance. The subject area is kinematics, specifically focusing on motion under constant acceleration.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the known variables of initial velocity, final velocity, and acceleration, and question which formula relates these to the unknown displacement. Some participants suggest considering relevant formulas that include acceleration.

Discussion Status

There is an ongoing exchange of ideas, with some participants offering guidance on identifying appropriate formulas while others emphasize the importance of allowing the original poster to engage with the problem independently. The discussion reflects a mix of encouragement and caution against providing too much direct help.

Contextual Notes

One participant mentions challenges with wording and expresses a desire for clarification, indicating potential difficulties in interpreting the problem statement. There is also a note about the importance of including units in future discussions.

Homework Statement



A car is traveling at = 24 . The driver applies the brakes and the car decelerates at = -4.0 . What is the stopping distance?

Homework Equations





The Attempt at a Solution



i just started my physics class and I have a horible teacher, i have never taken physics before and i think i just need a push in the right direction!
 
Physics news on Phys.org
You know the initial velocity, final velocity, and acceleration. Which formula has these 3 knowns as well as displacement (which is unknown, obviously)?
 
For the future you should write the unit

Hi rmax58! Welcome to PF! :smile:

What formulas do you know that include acceleration? :smile:
 
Hi minifhncc! :smile:

Please don't answer other members' questions for them …

especially when they haven't had time to reply to previous help (rmax58 is probably still asleep).

In this forum, we try to minimise the help, so that members can work the problems out themselves, and learn better.

And stop trying to re-interpret the questions … as you yourself said …​

Yeah I suck at word based stuff … =P
 
Deleted, there happy?

I might not be the best at wordings of questions but I still came 2nd in my cohort for Physics recently, so... =P
