Light gates may be used to measure the speed of projectiles, such as arrows shot from a bow. English longbows made of yew in the 1400s achieved launch speeds of 60 m/s. Determine the relationship between light gates and the accuracy required for sensing the times when the light gate senses the presence of the arrow.
