If coach hall wanted to calculate how fast his soccer players could run a 40 meter sprint, what tools would he need and how would he determine speed?

Well, the tools you would need is a measuring tape to make sure they measure 40 meters correctly. You will also need a stopwatch to time the player and to determine how fast they can run it. Lastly, you can use cones to notify player when they finish the run, but that is optional.

Hope I helped! :)
