Yes, you use a stopwatch.It was a math quiz for me, I wrote a stopwatch, and I got it correct.
Police measur speed with a radar gun. It uses the Doppler effect to find speed. You can measure distance traveled and use a stopwatch to measure speed yourself. You asked about velocity, however.

You use exactly the same instruments to measure speed in the metric system as you use in any other system. For example, a speedometer, or a distance measuring device and a stopwatch. The difference is that these devices are calibrated in metric units, instead of old-fashioned units.
Seeing as you are looking at speed, you could use a stopwatch.
The traditional instrument used to measure the time of a given run is the stopwatch.
