I wasn't sure where i should have posted this, since it's badminton related i didn't put it in the chit-chat forum. So here's what im looking for, I'm looking for a site that shows statistical data of speeds between the two. This is actually an assignment for a class im in. I'm supposed to find data on a topic that interests me and graph the data. So I would like to graph the speed of a bird and speed of a tennis ball. I think there's something in the faq that shows two numbers, the speed of the bird and tennis ball. There's also the length of how much the players ran.
