After we got everything set up my partner operated the projectile launcher and I stood behind the carbon paper prepared to catch the ball. We launched the projectile a total of five times. For each shot we measured the distance from the projectile launcher to the point where the ball landed. After we got the data for all five shots we calculated the initial velocity. Then we calculated the standard deviation to determine the uncertainty between the x- and y- components. Part II: For Part II we kept the projectile launcher at the same setting so that the initial velocity would be the same as in Part I. Then we adjusted the angle of the projectile launcher to 30 degrees. Then we used all of our data and the equations of motion to calculate the position of a box that would allow the projectile to land in that box.

Data The data taken below is based off of five shots from the projectile launcher. The origin for our data is the spot on the floor that is directly below the projectile launcher. Then we recorded the horizontal position from the point where the ball landed to the origin. After getting our data from Part I we calculated our uncertainties by using the equation for standard deviation. The x- component had a standard deviation of 4.1 cm.

###### "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.
