I. Lab #3 Introduction : In this experiment, our group was to prove that if an object was dropped at the same time a projectile was fired, the projectile would hit the object if it was within the maximum range of the projectile and if the projectile was aimed initially at the object. Data Analysis : For the first part we were to connect a metal plate to a device that would release it when the photogate stream was broken by the projectile. This would allow us to drop the plate at the same time the projectile was fired. In the second part we used a timing pad and the different firing powers to measure the time in the air and the initial horizontal velocity. We performed this twice for each range (short, medium, long) once at horizontal and once at an angle of 30 degrees. In order to shoot the plate, we aimed the launcher directly at the plate and fired it. At a distance of 1 M the projectile struck the plate near the top and the plate had fallen roughly .04 M. We performed it again at 1 M and got the same results. We then moved on to the horizontal firing. We took a practice shot on the short range power and then placed the timing target on the floor. When hit, we received that the projectile had an initial velocity of 6.02 m/s and had taken .496 seconds to reach the floor. We performed

### 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.
