Homework Help Overview

The discussion revolves around a problem in kinematics, specifically regarding the time it takes for a racer to travel a distance of 2(3.70)m, given a speed of 3.70m/s. Participants are exploring the implications of the problem's setup and the reasoning behind differing expected outcomes.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants are questioning whether the racer is moving at a constant velocity or if there is acceleration involved. There is also a focus on the interpretation of the problem as it relates to the expected answer versus the book's suggestion.

Discussion Status

The discussion is ongoing, with participants providing guidance on checking the problem's wording and considering different scenarios, such as uniform acceleration. There is no explicit consensus on the interpretation of the problem yet.

Contextual Notes

Participants note that the only information provided is the distance and the time for a single segment of that distance, leading to questions about the assumptions regarding the racer's motion.

If a racer travels 3.70m in one second. How long does it take for the racer to travel 2(3.70)m?

I was expecting 2s as the result but the book suggests square root of 2 to be the answer. I don't know why? Can anyone help me please.

Welcome to the PF.

Is the racer accelerating? What is the exact quote from the book?
 
Thank you! That's all the information given on the book. I suppose he's moving inthe constant velocity
 
I can only suggest you double check that you have quoted the question word for word as given in the book.
 
triple checked ;p

That won't work.

Assume uniform acceleration starting from rest.
