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 600 will travel the farthest. Joe
sets up the machine, and launches the first football at an angle of 300. He
then repeats this for each of the following angles: 350, 400, 450, 500, 550,
600, and 650. Joe measures the distance from the launcher to the spot
where the football first hit the ground. What is Joe's hypothesis? *
