Lab 5: Trajectories, Lab Partner: Jamie Lopez 09-19-16

2) In this lab, we will accomplish the use of understanding of projectile motion to predict the impact point of a ball on an inclined board.

3) In this experiment, we utilize our kinematic equations to predict of how far the ball will land when it leaves the edge of the table. Since the trajectory includes horizontal and vertical measurements, we will separate them to get our results. Here are the two experiments we tested to find the total distance the ball travels when it leaves the edge of the table. 

4) The first picture represents the first experiment to solve the total distance when it leaves the edge of the table. The second and fourth pictures represents the second experiment. The third picture is a carbon sheet of paper. We use the carbon paper to make the landing of the ball. We repeat the process of both experiment twice to make sure we get the same results. Our measurements from the ball's landing to the edge of the table is off by 1.5 cm since the area of the ball's landing wasn't always exactly on the same landing point.

6)Since we didn't use a logger pro device to determine a graph, here is an example of the ball's position and velocity the moment it leaves the edge of the table.


7) The pictures in number 5 are the calculations to determine the distance the ball leaves the table. Since we did have an uncertainty by 1.5 cm, our results still gives us an uncertainty around 1 cm. But our theory lets us predict correctly what we wanted to find by using the kinematic equations for projectile motion.
