The discussion revolves around a physics problem involving the stopping distance of a car under constant acceleration. The original poster presents a scenario where a race car decelerates at -11 m/s² from an initial speed of 45 m/s and inquires about the stopping distance, including a related question about a car traveling at half that speed.
Participants are actively engaging with the problem, with some providing resources while others express uncertainty about the applicability of those resources. There is a recognition that the problem can be approached without time, although clarity on the correct method remains unresolved.
The original poster indicates a lack of familiarity with the necessary formulas and expresses frustration with the guidance provided. There is an emphasis on finding a solution that does not involve time, which may impact the direction of the discussion.

merceb49 said:2. .. all i need is an answer
merceb49 said:ok well i do not know what type of formula, how do i get it?
Your observation that you do not need time to solve the problem is correct. The observation that all those equations involve time is not- look carefully.merceb49 said:thank you for the link, but none of those equations work, there is no time involved in the situation.
