This scenerio is made to go with the Article in "The Physics Teacher" magazine, December 2011, Volume 49, Issue9 pp. 554, called Additional Crime Scenes for Projectile Motion Unit. You will need subscrption to "The Physics Teacher" magazine to view the whole article. If you are familiar with the article, this is a variation of scenerio #1. I had to make a few changes to increase the measurement's accuracy. (Such as changing the room height in scenario 1 from 14 stories to 7 stories. This doubled the accuracy of the measurements on the computer screen.) Each time the page is loaded some of the objects being measured shift position.
