Can an athlete break the 100m dash record using time dilation?

[jinksys]

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?

WUT?

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.
