In a nutshell out project was basically to test the effect on intiial speeds affect on lost speed and final speed.. Since both me and my partner play this sport it is very helpful for us to know how to throw a perfect bounce pass. So when we took our data and put the video into video physics and tracked the ball, it spit out a graph for us to use. On that graph the Y intercept doesn't start at 0. It doesn't start at 0 because when you throw a bounce pass you throw it from your hip to the ground and it bounces off the ground and to your 

teammate. So in this case 0 will be when the ball hits the ground. That's why the y intercept starts above 0. Then quickly drops to 0 for because that represents the ball being bounced off the floor then into your teammates hands. The area underneath the curve in our graph represents how long it would take for the 

ball to get into our teammates hands. By also looking at the (trial) graph the area underneath the curve of the graph it represents how a bounce pass is short when you throw it into the ground but then bounces farther  after it comes back up. Some issues I would say that we came across would be that when we first had taken the data we had a really hard time being able to tell what had happened but with some help from a fellow classmate we were able to understand what had happened in our experiment and were able to  record the data.
