Right angle clamp Counter tray Bubble level Plumb bob Procedures First using a C-clamp we compressed the edge of the Mini Launcher to the edge of the table. Next we predicted where the steel ball would land upon its release from the launcher and marked that spot by taping the carbon and white paper to the floor.

Part I. Projectile Motion in a Horizontal Direction The Mini Launcher should be horizontal without any inclination. We loaded the ball and clicked the launder twice. Next we released the ball launching the projectile in a horizontal direction from the edge of the table, and noted where it stroke the floor using the carbon paper. Then using a plumb bob, we located the position on the floor that was exactly below the actual release point where the ball left the launcher and started the projectile motion in a horizontal direction and measured the distances y and x. We launched the ball five times and averaged the distance. After recoding the data we averaged x, to calculate v 0 . We then measured the height H above the floor from the bottom of the hole of the ring target and calculated the distance D where the target should be placed for the ball to pass through the hole. We launched the ball five times and averaged the results.

### 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.
