Can Time Dilation Help Break the 100m Dash Record?

Click For Summary

Homework Help Overview

The discussion revolves around the concept of time dilation in the context of an athlete attempting to break a 100m dash record by having their time measured from a moving spacecraft. The original poster questions the validity of this approach based on their understanding of physics principles related to time measurement in different frames of reference.

Discussion Character

  • Exploratory, Conceptual clarification

Approaches and Questions Raised

  • Participants discuss the implications of time dilation and length contraction, questioning the setup of the time measurement. There is a focus on understanding how time is measured by different observers, particularly whether the observer on the spacecraft uses a clock at rest with them or another reference.

Discussion Status

The discussion is ongoing, with participants exploring the foundational concepts of time dilation and its relevance to the proposed scenario. Some guidance has been offered regarding the need for background information on the relevant physics topics.

Contextual Notes

There is an implicit assumption that the athlete's idea hinges on the effects of relativistic physics, but the specifics of how these effects apply to the 100m dash scenario are still being examined.

Homework Statement


An athlete has learned enough physics to know that if he measures from the Earth a time interval on a moving spacecraft , what he finds will be grater than what somebody on the spacecraft would measure. He therefore proposes to set a world record for the 100m dash by having his time taken by an observer on a moving spacecraft . Is this a good idea?


Homework Equations





The Attempt at a Solution



An athlete has learned enough physics to know that if he measures from the Earth a time interval on a moving spacecraft , what he finds will be grater than what somebody on the spacecraft would measure.

To do this problem, first you need to have some understanding about time dilation and length contraction. It would be a good idea to get background information up on these subjects. That's wut.

Is the observer on the ship taking the time measurement using a clock on the ship or a clock on the ground?
 
The observer on the ship measures time with a clock that is at rest with him/her.
