that the launcher was able to send the ball. We measured the height the launcher was on the table, which counted as the y. We also measure how far away the ball landed on the floor, which counted as the x. By using the x and y measurements, I was able to find the v o . We recorded this information on Table 1. After this, I placed the ring target on the floor and predicted how far I would have to place it in order for the ball to be thrown perfectly through the hole. After a couple attempts of trial and error, my team finally got a good position. We measured this position’s distance from the hole of the ring target to the location of launch. We recorded this data on Table 2. For part two of the Projectile Motion experiment, we faced the clamped launcher towards the table and adjusted the angle of inclination to be 20 degrees. We chose the counter tray to be the surface where the ball hits the carbon paper in order to record the distance of contact. After setting up, we launched the ball about 5 times and measured the horizontal range for each launching. Using the angle, R and y=0, I calculated V o . I calculated these results on table 3. With this data, I calculated the distance D where the projectile will strike the floor. I recorded my results on TABLE 4 Results TABLE 1 Trial # 1 2 3 4 5 Average X 1.845m 1.85m 1.855m 1.86m 1.87m 1.856m Y= .87m v o = 4.39m/s

###### "Before using Course Hero my grade was at 78%. By the end of the semester my grade was at 90%. I could not have done it without all the class material I found."

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
