Joe the scientist wants to figure out the angle for throwing a football that will make it go the farthest. Joe borrows a football launching machine from the local university football team and he buys a brand new, football. Joe thinks that a football thrown at an angle of 60o will travel the farthest. Joe sets up the machine, and launches the first football at an angle of 30o. He then repeats this for each of the following angles: 35o, 40o, 45o, 50o, 55o, 60o, and 65o. Joe measures the distance from the launcher to the spot where the football first hit the ground. What is Joe’s hypothesis? *
