I'm conducting an experiment to determine the brachistochrone. The setup is going to involve an inverted cycloid shaped track about 5 or 6 feet long. I need a way to measure the time it takes for a marble to roll down the track and I need a more accurate method than manually operating a stopwatch. Is there a way to somehow synchronize two stopwatches, having one placed at the start of the track and one at the finish line, or are there any better ways of doing this?
