100m sprint -- world record Let's say you run the 100 meter sprint at the speed of light. You start exactly when the race begins. Thus, you have the fastest possible time for the 100m sprint. Your time would be: 100m * (1 sec /299,792,458 m) = .000000334 seconds If you started at the earliest possible moment, this would be the fastest possible time for the 100m sprint. Would there be any way to beat that time? Or is that the limit for the 100m world record? NOTE: This is all purely theoretical. I know that we cannot sprint at the speed of light. This is just for the sake of learning.
